have to disagree here!!!! codeine if taken in large inuff doses (i came up to 600 now, but 400mg is too good) if u smoke sum bud on it specially, can come to a potency of smack, in very different way, its less ''strong'' but more joyable and mind altering *if taken in high inuff doses and u handle it*
personally have no itches & side effects from 600mg...
i like codiene for one reason, if u smoke weed on say morphine or heroin or even tramadol (dont know bout oxy\hydro its very rare here), the high will not stream good together and will give u a heavy body load that u not really want.
for codiene, smoking weed\hash potantiates it in a way it does with exctasy for me!!!
