Answer:
Explanation:
Some people worry about the use of a particular drug—with the most common examples being alcohol, tobacco, marijuana, or prescription medications—leading to the use of more illicit drugs like cocaine.
Others may say people have individual responses to substance use in general, such as someone enjoying a few beers on the weekend.
Their occasional use never progresses to addiction, and they never touch an illicit drug.
Another person may also drink some beers and then find themselves sliding a slippery slope into daily drinking that has become an addiction, still never touching an illicit drug like heroin.
