What are careers that involve marijuana or just drugs in general?

Im 17, i love marijuana, idk if its the fact thats its illegal that makes me like it so much. but i know the history, chemistry, basically everything about it. i use it to help relax me when im stressed and to take the edge off. i have always wanted to pursuit a career that involved marijuana. i just have always had an interest in psychoactive drugs, and how they affect the mind. i want another persons viewpoint, and suggestions on some careers. if it also helps i have also though about psychiatry and being a therapist.
