Obviously, this would depend on what the person preferred to be involved with.  But, when it comes to prescription medication/opioids — probably some of the more commonly abused ones would be Vicodin for example.  Vicodin is a drug that's commonly prescribed when people get injuries and suffer from pain over a decent period of time and the people will start to take the Vicodin medication a lot of times become addicted.

First, they make you feel very good and in feeling good, they also avoid pain which is significant for those individuals who are addicted to opioids who are looking for pain relief.  So, Vicodin or Hydrocodone would be something that would be abused and people would try to get multiple prescriptions for them.  They will buy them on the black market.

Vicodin, Oxycodone, OxyContin

Another commonly abused opioid or prescription medication is Oxycodone or OxyContin.  This drug is again used for pain and it's something that is well-known to be abused and is well-known to have addictive characteristics and it's one of the drugs that I see a lot being sold on the black market.

People will get it and sell it to other people.  They even make a business out of it.  Once you get addicted, it's very hard to become un-addicted to this particular drug.

In addition to OxyContin, I think probably the most addictive drugs is heroin.  It's highly addictive and it is highly degrading to the human body and the human spirit.  Heroin is probably one of the worse drugs that an individual could be addicted to.  It's very expensive.

You don't need as much of it to get high and to get the effect that people are looking for.  People are ingesting it in many different ways.

Methamphetamine

Another, and I think one of the more commonly addictive opioids or drugs would be methamphetamine.  People become addictive and it pretty much destroys their lives, destroys their body, destroys their mind, their teeth and their health.  So, definitely methamphetamine is a highly addictive drug that gets people in a position where they cannot get off that particular jobs.

So, there's a whole slew of different drugs and I think it just depends on the person — how their body reacts to a particular opioid or drug and that's why there's so many different things that can be used to help or cure people from drug addiction.

But probably the biggest thing that I see and that is successful in helping an addict who continues to abuse drugs, is their own person will.  Because there's all sorts of things that can be done in helping a person who is abusing opioids/drugs, but that person themselves must want to become clean and sober.
