Addiction Marijuana a lot of years

Hello, good afternoon,

I tell you a little about my experience:

I have always been a very intelligent and diligent person in studies until at age 18, I got together with people that I shouldn't have been around. I started smoking joints straight at 18 and then tobacco while I waited for the joints to be made. I had never smoked until then and I took it with great desire, it was to put out one cigarette and light another.

I stopped getting together with the bad influences but the vices continued to be there and I kept them hidden from the eyes of my relatives, except my older brother, who is the one who has always supported me.

Currently more than 20 years have passed, I have been smoking since I was 18 and I am 40. I always or almost always smoke a few joints a day and sometimes I also use hard drugs secretly from my loved ones. What should I do? Marijuana, even a few joints, is it that bad? If they use it with cancer patients for something

They have told me about a clinic, that does spectacular therapies with animals in the middle of the mountain and I don't know if all these therapies would help me to stop my addictions once and for all.

I would appreciate some answer and conclusion of my problems exposed.
