In England I used to get mostly hash. I would break off a little chunk and swallow it before travelling. (As a passenger of course) It takes longer to feel, but the effects last longer than if smoked. I have also felt higher than normal after eating it. I used to make great chocolate chip, hash cookies before the extremely long bus ride to Amsterdam from where I lived. Made the LONG trip a lot more pleasant!
I also remember a guy getting cornered by the base police that popped a quarter of hash in his mouth to hide it. The police grabbed him and just watched him in his cell until he started getting very high. Then they got him to confess... That guy must have been loaded!
