Explain the three consequences for the drug scene from the tightening of restrictions on amphetamines in the 1960s and 1970s

What will be an ideal response?

First, the market began to sell legal, milder stimulants (usually caffeine or ephedrine) that were virtually indistinguishable to the eye from prescription amphetamines. One could not be prosecuted until new regulations were made that made it illegal to distribute any substance misrepresented as a controlled substance. Second, the price of amphetamines went up and quality declined. Therefore, people went back to using cocaine because it was believed to be less dangerous. Third, the number of illegal methamphetamine laboratories increased.
