Well nowadays kratom + weed is about as crazy as I get. lol. But yeah, back in the day I'd prefer dope or (more rarely) oxycodone
The only experience with morphine outside of a medical setting I have was one relatively brief period of time where one of my dealers sold these morphine tablets...they were instant-release tablets (something which seems kind of rare for morphine pharmaceuticals, at least in the USA, where most morphine products seem to be extended-release), 60 mgs IIRC. They were peach colored and had a little symbol of a crescent moon on one side of the tablet...I think that Actavis put them out. Man they were awesome, once you peeled off the outer coating and loaded it into a rig you were ready to go...the rush was almost uncomfortable with the "pins and needles" sensation but then you slipped into total opiated pleasure...
