Well Rican, thats a good question. Leon is somewhat correct when he says Codeine produces similar effects to heroin - it does, but not NEARLY as intense/bad for you. Ive never fucked with heroin and
NEVER will, EVER, so i cant tell you personally what the similarities are.
But for DXM - i wouldnt say its like an opiate... i dont want to get scientific or anything but its labelled as a Disassociative which basically cuts off the signals running from your brain to your body. It can still receive though, but i guess im trying to say that - it feels like you are lifted, kinda high, but more disconnected with reality and its a cool feeling. It doesnt really feel like any other drug.
Ive seen some DXM products at drug stores - in fact there is a lot, but HERE IS the thing, most of those products also have OTHER chemicals in them which can kill you if you take a lot - do NOT buy a product just because it says it has "30 mg of Dextromorphan" in it. You have to make SURE dxm is the only active ingredient.
But anyway - if youre looking for a good feelin codeine high, dont try DXM, its cool but it really is different, hehe.
If you want DXM buy dexalone, or Robitussens MAX strength, but if you choose robi it might come with a stomach ache as well. Dont trust em products at the stores.
And yeah XP i might want to study that shit more, like for a living
