Its almost impossible to convince a pothead that they have an addiction, most likely you will end up annoying them. Most potheads dont believe its addictive. But if they are doing fine in their life, whats the problem? Let them live it. Most people need some kind of a vice in this world.

I smoke a lot of weed, have for the last 10 years. Whenever I stop, I cant sleep properly and I crave it all day and will smoke more cigarettes to compensate but when I smoke weed I dont really smoke cigarettes. Altho I do mix tobacco in my joints so maybe thats why I crave a joint so bad. Im different to most potheads in that I do think its addictive, whether its the lifestyle or something chemical, but its one of the better addictions to have, it wont kill you as fast as others and stoners are pretty content ppl. Plus Ive lived in Amsterdam and have seen how its totally fine in an already functioning society and its really not that big of a deal at all.
