Hello @gooddream, you came up with something really interesting here. I once was addicted to tobacco and also did some research regarding. Tobacco is something which is way more addicting than any other drug and is available easily. Tabacco is the most consumed drug. Where snus is something which was discovered in 18th century and was used as an alternative of Tabacco.
Tabacco is still dangerous than snus and can actually lead to serious health problems.
Thanks a lot for sharing this post and I highly recommend people who smoke not do do this or promote this. Thanks a lot @gooddream I really appreciate your efforts and time for all of us.
