Im neither for or against it ,had my fair share of it in years gone by,but do agree with the majority on hard drugs do start of with cannabis,most if not all of the druggies in my hometown certainly did,and some of my friends too who are no longer living because of hard drugs.
They used to have street in amsterdam called needle alleyway,its now really a tourist walkthrough with shops ect but in the 90s it was full of smackheads hitting up openly,not a coincidence they started using hard drugs in amsterdam the worlds tokers heaven.
