In most instances, the side effects of cannabis consumption are fairly low-key. Even the occasional paranoid high and more frequent bouts of cottonmouth are usually nothing too grave.
But for a percentage of people, rare and more concerning cannabis side effects have made appearances. Below are three reactions to bear in mind.
For people with a family history of psychotic disorders, it has been reported that cannabis could act as a trigger to a psychotic break. While a definite direct cause is not yet proved, in European cities that sell high-potency marijuana, cannabis consumers were more likely to experience a first-time psychotic episode.
A subset of frequent cannabis users has also experienced cannabis hyperemesis syndrome, which seems to be linked to recurring weed use. More research is definitely required, but the condition tends to appear in people in their 30s and is characterized by nausea and vomiting.
