Dear Happy Doc, I suffer from Crohn’s disease, and use cannabis to treat it. I’ve been a regular user for fifteen years, but not a heavy one. One night a few weeks ago I had a joint and a couple of beers, and right after finishing the joint I went to pee and started to see stars, and when I left the toilet I lost consciousness for two seconds and fell down, hitting my head. What could have caused this? I had tests done (head, heart, blood pressure) and the results were ok…?
Hello. From your description, it seems that you underwent a short episode of low blood pressure, with momentary insufficient blood pressure to the brain. These episodes usually last from a few seconds to half a minute and without resulting symptoms (unless a person is injured when falling). There could be several causes. Combining cannabis with alcohol certainly has a “stronger” effect than cannabis alone, because its effects are multiplied. Also the THC content in cannabis which is smoked can vary from plant to plant, so the effects are varied. Other factors which could come into play are the body’s overall physical fatigue, psychological frame of mind, or not keeping one’s liquids up (alcohol is a dehydrator).
Also, regarding Crohn’s disease: cannabis certainly can help autoimmune diseases, but smoking is not the most suitable method of ingestion for treatment. I rather recommend vaporizing or oral consumption – cannabis extract in oil, in capsules – or even suppositories.
