Thanks for sharing your thoughts - I've used cannabis for about 30 years now, and my experience differs from yours considerably.
Sure, there are times that it can make me lazy (sometimes the difference between sativa and indica), but mostly, it just adds a filter to my regular existence. I still function nearly exactly the same way as I do whilst not under the influence, it just allows me to tap into creative thought a little easier overall. It also lowers inhibitions, which just makes social situations more fun in general.
My experience with alcohol, on the other hand, is not as positive. It makes my mind sluggish, both in the moment, as well as the next day, if I've had a little too much to drink.
We are fascinating creatures, in that our individual experiences with various substances can vary so widely, wouldn't you agree?
