OK so swim has been smoking weed for about 4 yrs now, 2 years heavily. Swim has also done various other drugs such as E, coke, shrooms and salvia but all in small amounts and hasnt done any of the others in a while. swim noticed that alot of times when he would smoke, he would get a kind of shakes or tremors, these where never to bothersome but definetly not welcome. Then Swim noticed he could never keep a steady hand and would shake profusely even when he was not high, whats worse it is sometimes so bad that other people notice it and constantly ask if swims. He is not positive but swim believes that his sober shakes came from smoking weed, it is the only thing he can attribute it to. Another thing that makes him think this is that he has not smoked for about 5 dews now, hes been smoking every day for 2 yrs, and his shakes have decreased every day since he quit. So what do yall make of this?

P.S. Sorry for the long winded post and thanks in advance!
