How much THC is in that candy?
Just a few years ago, this wasn’t true. As soon as I mentioned the need to get a drug screen, my patients would get a nervous look on their face, often confessing marijuana use before the test results came back and begging me not to tell their parents.
My patients now recognize marijuana as a drug—a medical drug, that is. They tell their parents how it helps with depression and anxiety. And I tell them I believe them. Marijuana probably does help them feel better. I also tell them we have other drugs to treat depression, anxiety, and pain, drugs that are better regulated and have risk profiles that are better understood, drugs with standard concentrations and doses. Nicotine, too, is a stimulant that can improve ADHD symptoms, but we don’t recommend smoking as an ADHD treatment. We have better drugs for that, too.
Recreational marijuana is losing its taboo identity now that it is legal in Washington State and Colorado and now that sixteen states plus the District of Columbia have decriminalized possession of marijuana for personal use.
I spent a summer in college doing cannabinoid research at the NIH, trying to understand the effects of marijuana in the brain. I’m the first to admit that cannabinoids are a promising class of drugs. But marijuana is just that—a drug—and its recreational use should still be taboo Here’s why:
1) Is it synthetic? A patient came into my ER hallucinating with tales of a very bad trip. He showed me his “marijuana,” a bunch of leaves rolled into a joint. And then his drug screen came back negative. His was synthetic marijuana, a bunch of herbs sprayed with some unknown chemical. Synthetic marijuana often contains laboratory manufactured chemicals that have the same effect as THC, the psychoactive ingredient in marijuana. But sometimes the product is actually laced with bath salts or other street drugs. I never really know what my patients have taken, which makes it hard for me to treat them.
2) How much THC is in that candy? My four-year-old saw a brownie at a beach bake-sale and started begging me to buy it for him. The guy selling it looked me directly in the eyes and shook his head. I knew what he meant. Marijuana brownies, cookies, and jolly-rancher-like hard candies are common now. The problem is that you just don’t know how much THC is in the treats. Some contain much higher concentrations than one joint, and who can eat only one cookie? The result is an overdose effect that can land people in the ER Dr. Dan Hehir, an ER physician at Telluride Medical Center in Colorado recounts stories of recreational marijuana overdoses, especially in marijuana baked goods and candies.
3) Infertility: Marijuana use reduces fertility in both men and women (but no, marijuana is not a form of birth-control). Anandamide is an “endogenous cannabinoid,” a THC-like chemical that is naturally occurring in all of our bodies. Anandamide also helps human conception, giving signals to sperm to “hyperactivate,” or swim faster so they can penetrate the egg. (Anandamide is also in chocolate, perhaps one reason people often use the words “sex” and “chocolate” in the same sentence). Using marijuana sends signals to sperm to hyperactivate too early, so they are all burned out before they ever reach the egg (pun intended). Marijuana use is also known to reduce the volume of sperm production. If women use marijuana, the THC is in their cervical fluids, also causing hyperactivation of sperm and reducing the likelihood of conception.
4) Impaired memory: What was that? That’s right, marijuana use impairs memory, a critical skill for academic success (marriage, too). Most of the time memory loss is subtle, just enough to cause a drop in school grades, but occasionally memory loss can be profound. A case report published last month describes a patient with marijuana-induced transient global amnesia.
5) Paranoia: Marijuana can cause paranoia, especially in patients who have underlying mental illness. In a study published in July, 2014, intravenous THC was administered to 121 patients. The authors write, “THC significantly increased paranoia, negative affect (anxiety, worry, depression, negative thoughts about the self), and a range of anomalous experiences, and reduced working memory capacity.”
6) Thrush: Thrush, or an oral yeast infection, can result from chronic marijuana smoking. There’s a reason why some people call thrush “trench-mouth.” A white film grows over the inside of your mouth and tongue.
7) We don’t really understand most of the risks of marijuana: This is perhaps the biggest problem with Marijuana– it’s really hard to study it. Would you take a drug that is poorly researched? Research on marijuana is difficult because it is illegal in most states. There are possible associations with some forms of cancer, but because most marijuana users are also tobacco users it is difficult to determine the effects of the marijuana alone.There seems to be an association with lung disease, especially among people who smoke marijuana long term. Its addictive nature is perhaps most controversial. The bottom line is we don’t understand this drug as we do most pharmaceuticals.
Taboo or not, my patients take marijuana because they are desperate. Desperate to dull the pains of stress, anxiety, depression, and the hardships of life. Legalization of recreational marijuana is not the solution to these ills. If you have a teen who is stressed or depressed, you should be aware of the 8 other ways teens are trying to dull the pain in ways that are very dangerous to them.
