<---- just now actually reading the thread see all these references to "slugger" and got confused. Just realized I have that poster on ignore. Conversation was very confusing.
Through my time in college and in my professional years I've known a lot of people that smoke weed. The people that smoked in college, sat on the couch, watched tv all day, didn't go to class, failed out, and so on were lazy POSs when they WEREN'T high. The weed didn't make em lazy... their lazy made it ok for em to smoke weed IMO. I've also known people with families of their own that smoke every day and are some of the most productive people when high. One guy built the back deck to his house while high the entire time. Some of these folks will get high and clean their entire house. Some others will get high and sit in one spot for 3 hours while barely mustering the energy to blink.
Don't know if it's a gateway or not, but CAN say with fair certainty that it doesn't turn people into lazy hunks of crap. Those people were likely lazy hunks of crap before and the weed just magnifies it. All the people I've ever known that smoked also ONLY smoked. They weren't sneaking coke, heroine, meth, etc and they had been all smoking for well over 10 years.
