When i smoke marijuana i just get a lump in my throat now i used to have panic attacks but now i don't i know its a withdrawal will it ever go away ?

It may or may not: Possible effects of marijuana: anxiety, depression, fear, panic , delusions, hallucinations, losing touch with reality, inattentiveness, short-term memory problems, disturbances of thought processes. You might feel tired, have poor concentration, slowed reaction times & slowed problem solving. The panic attacks may or may not resolve. Recommending seeking psychiatric at this point.
