greetings friend,cannabis can stay in your system and be noticed on the drug test
for over one month. Cannabis is dangerous to both the cardiovascular and respiratory systems, and while many people seem to have relief of any kind of symptoms or pain or nausea
with cannabis, it is not study and is not known to be safe for effective brew clinical trial so far, so as a physician I would not recommend doing it even periodically. It is also habit-forming and highly addictive. Cheers.
