Hi, since childhood, confronted with some situations (taking an injection, withdrawal, etc), I start to feel (not always) dizzy, weak and pale as if I was about to faint.
But there was two times in my life when I actually fainted for seconds:the first one was watching a movie dealing with health related issues (health and the human body was always a stressful subject to me) and I started to feel hot and so uncomfortable that I had to leave the cinema and I fainted right there at the exit. The second time was after consuming cannabis, I was sitting down and I started to feel strange, my friends were saying I was becoming pale and I stood up and fainted again for seconds.
On the two occasions I became ok after waking up and I never give much thought about it, but I just read this passage on a site related to medical marijuana and I became a little worried:
"The overall effect of cannabis use on the frequency of heart attacks is unknown. This can only be ascertained in longitidudinal epidemiological studies. There are some studies and case reports that support the assumption that cannabis use may be harmful in people with coronary disease and may trigger a heart attack. However, this seems to be a very rare event. Cannabis will not cause a heart attack in a healthy person.
There are some pharmacological effects of cannabis that may act preventive and some that may be damaging.
Factors that may be damaging:
- Changes of blood pressure. Cannabis may cause the blood pressure to increase when the person is lying down, and to decrease when the person stands up."
What kind of damage are they referring to? can it be brain damage (due to low oxygen in the brain) or heart damage?
If any of the physicians on this forum could help I would greatly appreciate.
