1 00:00:02,040 --> 00:00:07,160 Speaker 1: Welcome to brain Stuff from How Stuff Works, Hey, brain Stuff, 2 00:00:07,200 --> 00:00:11,160 Speaker 1: Lauren vogebam here. After five plus years of deep researching 3 00:00:11,200 --> 00:00:15,720 Speaker 1: potential medicinal uses for cannabis, Sanjay Gupta, neurosurgeon, professor at 4 00:00:15,720 --> 00:00:19,200 Speaker 1: Emory University School of Medicine in Atlanta, and most famously 5 00:00:19,400 --> 00:00:23,360 Speaker 1: medical correspondent for cable news giant CNN, has settled firmly 6 00:00:23,480 --> 00:00:27,600 Speaker 1: on this conclusion. We'd works, and not for everybody, but 7 00:00:27,760 --> 00:00:30,800 Speaker 1: for a lot of people it can ease pain, reduce inflammation, 8 00:00:31,120 --> 00:00:33,919 Speaker 1: and for many who struggle with opioid addictions, it can 9 00:00:33,920 --> 00:00:37,480 Speaker 1: help them kick their habits by tamping down the nausea, insomnia, 10 00:00:37,560 --> 00:00:42,480 Speaker 1: and other symptoms that characterize opioid withdrawal. Very possibly, cannabis 11 00:00:42,479 --> 00:00:46,800 Speaker 1: may help heal brain damage caused by opioids too. Gupta 12 00:00:46,880 --> 00:00:49,600 Speaker 1: has not always believed this. He wrote a piece for 13 00:00:49,640 --> 00:00:52,800 Speaker 1: Time Magazine in two thousand nine outlining his opposition to 14 00:00:52,840 --> 00:00:56,880 Speaker 1: the legalization of pot even for medicinal use. His turnabouts 15 00:00:56,880 --> 00:00:59,400 Speaker 1: since then has made him an unlikely ally of the 16 00:00:59,440 --> 00:01:02,240 Speaker 1: pro can this crowd and put him publicly at odds 17 00:01:02,240 --> 00:01:04,720 Speaker 1: with a government that still places cannabis in the same 18 00:01:04,760 --> 00:01:08,600 Speaker 1: class of drugs as heroin. And LSD Dr Sanjay Gupta, 19 00:01:08,680 --> 00:01:13,160 Speaker 1: CNN star practicing brain surgeon and medical marijuana advocate. Who 20 00:01:13,200 --> 00:01:16,840 Speaker 1: would thunk it? Gupta says, I don't really know that 21 00:01:16,920 --> 00:01:19,720 Speaker 1: I see this as being an advocate. I think for me, 22 00:01:19,880 --> 00:01:22,360 Speaker 1: it was not advocacy journalism as much as it was 23 00:01:22,440 --> 00:01:27,360 Speaker 1: evidenced based journalism that hopefully spoke truth to power. Gupta's 24 00:01:27,400 --> 00:01:30,280 Speaker 1: about face on cannabis, or maybe it's better described as 25 00:01:30,319 --> 00:01:34,039 Speaker 1: a slow, steady, deeply thought out awakening, is grounded in 26 00:01:34,200 --> 00:01:38,279 Speaker 1: years of journalistic research highlighted in the CNN documentary Weed. 27 00:01:38,920 --> 00:01:42,240 Speaker 1: The fourth installment of the series Weed four Pot Versus Pills, 28 00:01:42,480 --> 00:01:45,280 Speaker 1: examined the use of medical cannabis who help solve America's 29 00:01:45,280 --> 00:01:50,000 Speaker 1: addiction to opioids. It's a crisis crying for answers. According 30 00:01:50,000 --> 00:01:52,440 Speaker 1: to the National Institute on Drug Abuse, more than a 31 00:01:52,520 --> 00:01:55,920 Speaker 1: hundred and fifteen Americans die every day from opioid overdose, 32 00:01:56,280 --> 00:02:00,200 Speaker 1: usually prescription painkillers, heroin, or synthetic opioids Like to Know. 33 00:02:00,960 --> 00:02:03,720 Speaker 1: One study puts the economic burden of the epidemic at 34 00:02:03,720 --> 00:02:08,120 Speaker 1: more than seventy eight billion dollars a year. At least 35 00:02:08,200 --> 00:02:10,880 Speaker 1: part of the solution to combating the opioid crisis to 36 00:02:11,000 --> 00:02:14,960 Speaker 1: a growing number of researchers and doctors, including Gupta, is cannabis, 37 00:02:15,200 --> 00:02:20,399 Speaker 1: a long stigmatized drug used recreationally and therapeutically. Those researchers 38 00:02:20,400 --> 00:02:23,000 Speaker 1: and doctors are just beginning to unlock what happens when 39 00:02:23,040 --> 00:02:25,440 Speaker 1: pot hits the brain and how that can help break 40 00:02:25,440 --> 00:02:29,079 Speaker 1: an addiction to opioids. Opiates block the transmission of pain 41 00:02:29,120 --> 00:02:31,680 Speaker 1: signals to the brain, and they can be very good 42 00:02:31,760 --> 00:02:34,720 Speaker 1: at it. The problem is that the drugs are highly addictive, 43 00:02:35,120 --> 00:02:37,280 Speaker 1: users need more and more to get the same relief, 44 00:02:37,400 --> 00:02:41,280 Speaker 1: making them extremely dangerous. They can, Gupta explains, in weed 45 00:02:41,320 --> 00:02:44,920 Speaker 1: four actually turn off the body's natural instinct to breathe, 46 00:02:45,200 --> 00:02:48,840 Speaker 1: leading to tens of thousands of deaths a year. Gupta says, 47 00:02:49,160 --> 00:02:51,720 Speaker 1: opiates tend to cause this disruption in an area of 48 00:02:51,720 --> 00:02:55,240 Speaker 1: the brain around these glutamate receptors. I liken it to 49 00:02:55,400 --> 00:02:57,880 Speaker 1: having two big cities, New York in Chicago, and you 50 00:02:57,919 --> 00:02:59,880 Speaker 1: need to send these signals back and forth, fire air 51 00:03:00,000 --> 00:03:03,040 Speaker 1: planes to these two cities, and suddenly all the transportation 52 00:03:03,120 --> 00:03:06,480 Speaker 1: is down once hooked on opiates, and that can happen 53 00:03:06,520 --> 00:03:08,720 Speaker 1: as quickly as in a couple of weeks addiction is 54 00:03:08,840 --> 00:03:11,760 Speaker 1: very difficult to break, possibly because of the damage the 55 00:03:11,800 --> 00:03:14,040 Speaker 1: drugs do in a certain area of the brain, the 56 00:03:14,240 --> 00:03:18,359 Speaker 1: prefrontal cortex. Gupta explains that part of the brain is 57 00:03:18,440 --> 00:03:20,920 Speaker 1: sort of a judgment area where you start to learn things. 58 00:03:21,360 --> 00:03:23,400 Speaker 1: Some of the wisdom that has come out recently is 59 00:03:23,440 --> 00:03:25,880 Speaker 1: that even if you stop taking the opiates, you don't 60 00:03:25,919 --> 00:03:28,520 Speaker 1: necessarily heal that part of the brain. You're still at 61 00:03:28,600 --> 00:03:31,480 Speaker 1: risk of relapsing in some ways. The brain is not 62 00:03:31,600 --> 00:03:35,800 Speaker 1: able to remember the negative impact of the opiates. Cannabis, 63 00:03:35,880 --> 00:03:39,240 Speaker 1: like opiates, also blocks pain signals, Gupta says, but it 64 00:03:39,280 --> 00:03:42,640 Speaker 1: also reduces inflammation that can lead to further pain. And 65 00:03:42,800 --> 00:03:46,160 Speaker 1: the real advantage of cannabis for opioid addicts, Gupta says, 66 00:03:46,200 --> 00:03:48,880 Speaker 1: and here he points out the groundbreaking research of Dr 67 00:03:48,960 --> 00:03:51,760 Speaker 1: Yasmin Heard, the director of the Addiction Institute at Mount 68 00:03:51,800 --> 00:03:54,920 Speaker 1: Sinai in New York. Maybe that the cannabidiol or c 69 00:03:55,160 --> 00:03:58,480 Speaker 1: b D compound in the plant can fix the receptors 70 00:03:58,560 --> 00:04:01,000 Speaker 1: damaged in the brain from opioid use and can make 71 00:04:01,040 --> 00:04:05,080 Speaker 1: communication in the brain whole again. Gupta says. The idea 72 00:04:05,160 --> 00:04:07,440 Speaker 1: that cb D can heal the deceased brain of an 73 00:04:07,440 --> 00:04:10,520 Speaker 1: addict was the real takeaway for me. There's nothing else 74 00:04:10,520 --> 00:04:12,120 Speaker 1: that we know of that can really do that in 75 00:04:12,160 --> 00:04:15,480 Speaker 1: the way CBD does. One of the more than four 76 00:04:15,560 --> 00:04:18,800 Speaker 1: hundred chemical compounds in the cannabis plant, c b D 77 00:04:19,080 --> 00:04:22,520 Speaker 1: is used often for medicinal purposes in children for diseases 78 00:04:22,560 --> 00:04:25,440 Speaker 1: like epilepsy, and is legal even in seventeen of the 79 00:04:25,520 --> 00:04:30,240 Speaker 1: most cannabis opposed states. CBD does not contain the psychoactive 80 00:04:30,279 --> 00:04:32,960 Speaker 1: part of the plant, known as th HC that produces 81 00:04:33,040 --> 00:04:37,040 Speaker 1: the high of cannabis use. The pro cannabis crowd points 82 00:04:37,040 --> 00:04:40,240 Speaker 1: out that no one has ever overdosed on cannabis or CBD, 83 00:04:40,680 --> 00:04:44,240 Speaker 1: making it infinitely more preferable to other addiction breaking therapies 84 00:04:44,240 --> 00:04:47,120 Speaker 1: that use opiates like sobox zone or methadone to wean 85 00:04:47,200 --> 00:04:51,479 Speaker 1: addicts off stronger opiates like heroin. Still, cannabis use is 86 00:04:51,520 --> 00:04:55,200 Speaker 1: not without its dangers, especially for younger people with developing brains. 87 00:04:55,240 --> 00:04:59,200 Speaker 1: Gupta says cannabis can be addictive and the psychoactive part 88 00:04:59,240 --> 00:05:01,680 Speaker 1: of the plant can hair a motor function and judgment. 89 00:05:02,920 --> 00:05:06,440 Speaker 1: Despite cannabis negatives, the biggest hurdle that we'd advocates face 90 00:05:06,600 --> 00:05:11,039 Speaker 1: is clear the plant remains a federally regulated Schedule one drug. 91 00:05:11,839 --> 00:05:14,880 Speaker 1: Though many states have legalized CBD and have approved cannabis 92 00:05:14,920 --> 00:05:18,240 Speaker 1: for medicinal uses, and some have even ocated for recreational 93 00:05:18,360 --> 00:05:21,200 Speaker 1: or otherwise personal use, it is still illegal on the 94 00:05:21,240 --> 00:05:25,320 Speaker 1: federal level. Many in the current presidential administration seem hell 95 00:05:25,400 --> 00:05:28,560 Speaker 1: bent on keeping it that way. The nation's top drug 96 00:05:28,640 --> 00:05:32,279 Speaker 1: enforcement official, Attorney General Jeff Sessions, has spoken out forcefully 97 00:05:32,279 --> 00:05:35,200 Speaker 1: against the legalization of cannabis and seems defiant in his 98 00:05:35,279 --> 00:05:38,919 Speaker 1: opposition to the work of Mount Sinise Herd and others. 99 00:05:38,960 --> 00:05:41,599 Speaker 1: Sessions apparent reluctance to look at the potential good of 100 00:05:41,640 --> 00:05:45,320 Speaker 1: cannabis is not unusual. Many people still see cannabis as 101 00:05:45,320 --> 00:05:48,479 Speaker 1: a gateway too harder drugs, a theory that's been debated 102 00:05:48,520 --> 00:05:52,400 Speaker 1: for years, debunked by some and revived by others through 103 00:05:52,440 --> 00:05:55,240 Speaker 1: the work of Herd and many others. Though it's becoming 104 00:05:55,320 --> 00:05:58,080 Speaker 1: much more difficult to blindly accept the old way of 105 00:05:58,120 --> 00:06:00,880 Speaker 1: looking at cannabis, Good to stands as one of the 106 00:06:00,920 --> 00:06:03,680 Speaker 1: more public examples of someone who has accepted new evidence, 107 00:06:03,960 --> 00:06:06,279 Speaker 1: and he's glad to share his findings with the powerful. 108 00:06:06,800 --> 00:06:10,040 Speaker 1: In April, he wrote an open letter to Sessions after 109 00:06:10,120 --> 00:06:14,960 Speaker 1: Sessions repeatedly turned down Gupta's requests for interviews. Research by 110 00:06:15,040 --> 00:06:18,200 Speaker 1: Herd and others, including University of California, San Diego and 111 00:06:18,320 --> 00:06:21,159 Speaker 1: entusiologist Mark Wallace, who has been looking at cannabis as 112 00:06:21,160 --> 00:06:24,440 Speaker 1: an alternative pain reliever for more than twenty years, continues, 113 00:06:24,839 --> 00:06:27,800 Speaker 1: even though studying the medicinal uses of cannabis is difficult 114 00:06:27,839 --> 00:06:31,520 Speaker 1: because of its status as a Schedule one drug. Gupta says, 115 00:06:31,560 --> 00:06:34,000 Speaker 1: I think it's one of those situations where everybody who 116 00:06:34,120 --> 00:06:37,599 Speaker 1: is responsible in this whole discussion wants more data. The 117 00:06:37,640 --> 00:06:40,159 Speaker 1: situation I think we find ourselves in is there isn't 118 00:06:40,200 --> 00:06:43,279 Speaker 1: a real mechanism by which to obtain that data given 119 00:06:43,320 --> 00:06:47,680 Speaker 1: the regulations right now around medicinal marijuana. The debate on 120 00:06:47,720 --> 00:06:50,520 Speaker 1: how to research cannabis, or even if we should study 121 00:06:50,560 --> 00:06:54,920 Speaker 1: it continues too, though a showdown may be coming. In June, 122 00:06:55,839 --> 00:06:59,279 Speaker 1: the US Food and Drug Administration approved a CBD based drug, 123 00:06:59,360 --> 00:07:02,679 Speaker 1: a pity elect for the treatment of epilepsy, that puts 124 00:07:02,720 --> 00:07:05,640 Speaker 1: the ft A in a strange position a federal agency 125 00:07:05,720 --> 00:07:08,720 Speaker 1: giving the go ahead to a cannabis derived drug even 126 00:07:08,760 --> 00:07:12,880 Speaker 1: as it remains illegal on the federal level. Researchers and 127 00:07:12,920 --> 00:07:15,760 Speaker 1: proponents like Gupta, hope that this will push the government 128 00:07:15,800 --> 00:07:20,320 Speaker 1: to reschedule cannabis as a less dangerous drug. Rescheduling would 129 00:07:20,360 --> 00:07:24,560 Speaker 1: make research easier and perhaps someday unlock more federally approved 130 00:07:24,640 --> 00:07:27,160 Speaker 1: uses for a plant that may yet play a major 131 00:07:27,200 --> 00:07:30,520 Speaker 1: part in bettering even saving thousands of American lives from 132 00:07:30,560 --> 00:07:35,120 Speaker 1: opioid addiction. Gupta said, over the next year, my guess 133 00:07:35,200 --> 00:07:37,920 Speaker 1: is We're going to see a significant transformation with regard 134 00:07:38,000 --> 00:07:41,200 Speaker 1: to medical marijuana in this country. We're seeing something that 135 00:07:41,240 --> 00:07:43,920 Speaker 1: I've never seen before in my medical life, an entirely 136 00:07:43,960 --> 00:07:46,360 Speaker 1: new class of medications that could be used to treat 137 00:07:46,440 --> 00:07:54,120 Speaker 1: a wide variety of things.
