In 1999, the United States National Academy of Sciences, Institute of Medicine released the most comprehensive review of medical cannabis to date. They found that cannabis is not a completely benign substance. It is a powerful drug with a variety of effects.

However, except for the harm associated with smoking, the adverse effects of cannabis use are within the range tolerated for other medications. Thus, the safety issues associated with cannabis do not preclude some medical uses.

Cannabis is a non-toxic, non-lethal medicine. Researchers have failed to find a lethal acute dosage of cannabis, and have found that the doses of long-term cannabis required to produce toxicity and death in animals were so high it would be nearly impossible for a human to consume such quantities via ingestion or inhalation.

Medical cannabis users do experience more adverse side effects than patients receiving placebo. According to a recent review article published in the Journal of the American Medical Association, the most commonly reported side effects are dizziness, dry mouth, nausea, fatigue, sleepiness, euphoria (excitement and happiness), depression, vomiting, diarrhea, disorientation, anxiety, confusion, impaired balance, hallucination, and paranoia. Strangely, that review article failed to include impaired short-term memory, a commonly reported side effect (sometimes adverse, sometimes beneficial) in our patients.
