Pleasure is addictive. Distraction is addictive. Relaxation is addictive. If you're not a totally balanced person and you're not living a fulfilled life, weed can often fill a big gap for people. If people can't relax, they smoke. If they have something constantly on their mind and it's driving them crazy, they smoke for distraction, for escape. In my experience, the people who can take it or leave it are the people who came from the perfect, happy families. People who don't have pain or a sense of existential dread..Is weed inherently addictive? No..but what it offers is addictive, especially if you've no other way of achieving those feelings
