I have never been addicted to any sort of prescription drug and I've hardly taken any in the first place as I am seldom ill. What I would like to know from the community is, how and why does one become addicted to prescription drugs? What do they contain that can cause this and what sort of effects do these drugs have when taken excessively? I know that they obviously don't do what illegal drugs do, so what motivates one to take more? I would also like to know how people have access to the drug, as I was always under the assumption that pharmacies would regulate this kind of thing. Thank you for any feedback.
