Compared to those who don't use marijuana, those who frequently use large amounts report the following: Breathing problems. Marijuana smoke irritates the lungs, and people who smoke marijuana frequently can have the same breathing problems as those who smoke tobacco.

Researchers so far haven't found a higher risk for lung cancer in people who smoke marijuana. 8 An overdose occurs when a person uses enough of the drug to produce life-threatening symptoms or death. There are no reports of teens or adults dying from marijuana alone. However, some people who use marijuana can feel some very uncomfortable side effects, especially when using marijuana products with high THC levels.

Nabiximols (Sativex) for multiple sclerosis (MS) THC acts on specific brain cell receptors that ordinarily react to natural THC-like chemicals. These natural chemicals play a role in normal brain development and function.

CBD. This is a psychoactive cannabinoid, yet it’s non-intoxicating and non-euphoric, meaning it won’t get you “high.” It’s often used to help reduce inflammation and pain. It may also ease nausea, migraine, seizures, and anxiety. ( Epidiolex is the first and only prescription medication to contain CBD and be approved by the Food and Drug Administration, or FDA. This medication is used to treat certain kinds of epilepsy.) Researchers are still trying to fully understand the effectiveness of CBD’s medical use. It's likely most of these products – even those called CBD oils – will be illegal to possess or supply. There's a good chance they will contain THC, and may not be safe to use.
