My friend and I got really bored one day, and at that time, we were able to buy a pack , and went into the woods and stood there,
smoking one
cigarette after another. Ha, Ha, we probably turned greener than the grass. Yet , at that time frame in life, we were bored with nothing to do, and kept at it for about a week until we got hooked.
You asked does it lead to other drugs?
No, , not if they find a coping mechanism to overcome the feelings that need to be worked out.
