Hello Doctor, I am asking this question on behalf of my friend who is now addict to "Bhang" or "Cannabis". These days his reaction toward any situation is very agressive and act like insane. Red Eyes, fast heart beats, depression. are very common now a days. I would like to know, how can he get recovered from this and is there any medicine to get rid of this Bhang addiction. Also, does he need admission in rehab center?
