Anyone can go to the store and by over the counter drugs. They’re the drugs you get when you’re sick or have a cold. (Ibuprofen, mucinex, cough syrups, Advil, etc)
Recreational drugs are illegal drugs that people take/use for fun and just to get high. They don’t need them but they use them illegally anyway. They can be drugs like cocaine, heroin, meth, etc. OR they can be prescribed drugs that people get when they DONT have a prescription. So they’re still taking them illegally cuz the drugs aren’t meant for them. Those can be drugs like OxyContin, hydrocodone, Vicodin, morphine, tramadol etc
Prescription drugs are drugs you get from your doctor. You go to see them and they prescribe you a drug for whatever problem you have and you can only get a specific amount for a specific period of time. They’re not meant for anyone else to take, only you.
