Can substances interact and change?

[Tim3]

Hello,

Is it possible that depending on the substances in your body, and or lets just say there's substance a. and you had other stuff like coffee with it, for example. could the other substances i.e: caffeine interact with the other substance changing its molecule structure into something making it into a different drug (but similar of course)

thanks.

One word: cocaethylne

Ok three words and some symbols: alcohol + cocaine = cocaethylene

That's the one example that I know about, but I'm sure it happens with other drugs as well (some we probably don't even know about yet).

most of them don't combine to any appreciable effect. that is, combining cafeine nd alcohol won't form many new compounds, you'll just be subject to caffeine plus alcohol's effects.

cocaine being a metabolically labile ester is kind of different. so is its close friend methylphenidate. but even then the amount of metabolic conversion to ethyl esters in the presence of alcohol is little more than a curiosity.
