What exactly should i study in college to have the skills to make and isolate high quality drugs from plants and chems?

clandestine

Drugs from doctors may hurt people. Natural medicine maybe better. Cleaning up the environment college degree may help alot. There are toxic waste in ocean/lakes that need help.

I would THINK, a major in Botany. No?

If you want to "make" the drugs, in test-tube size quantities, you need to take biochemistry and organic chemistry, and lab chemistry, and lots of it. If you want to make it in large quantities, like for sale, you need to take chemical engineering, and lots of that too. If you're going to sell the stuff, you need lots of years in law school, many millions of dollars, years of time, plus the services of a chemical testing and certification company.

Thanks !
