did you just come in from the 50s in a time machine or something?
also I have never heard of or saw anyone smoke weed then say hmm, you know I'd like to try some blow. Alcohol, yes all the time.
In my experiences the way the MJ is smoked could lead to addiction. People that smoke out of tobacco (blunts and wraps) have a hard time quitting because they become addicted to the nicotine and associate that with the MJ cigar. The people that smoke out of papers or bowls don't become addicted to anything and stop all the time. It's a habit and that is a lot easier to break than addiction. Just my opinion based on experiences.
Gregory imo is just an idiot.
