hash pen is the best, just press a button and get blasted, no more flicking a lighter over and over while driving w my knees. smoke a lot of shatter or wax, not a whole lot of weed, though i usually do keep some on hand for smoking around the house for a change of pace. but driving, its always hash, the smell is minimal and it doesnt cling to everything for 20 minutes the way weed smoke does. the only negative, if it truly is one, is learning the right dosage, its way too easy to get TOO high, hahaha. (or at least too high for working). if you smoke the same way you might step outside at work and suck down a bowl really quick, you'll turn yourself retarded. i limit myself to something like two hits an hour if i have to actually accomplish anything with my day.
