There are a number of ways to approach this. Because there are people that use these strong painkillers to actually live their day to day lives. Some people use them long after their problem with the pain due to their own reason mostly from how addictive pain killers can be. I know i felt that way after a surgery when i was put on strong pain killers. But at the same time i know what they were doing to me so I only took what I had when i needed them. So should those people taking pain killers be punished more harshly after if they are having addictive issues with them after. No they should be put into a state of recovery where they are slowly taken off the drug so they can get back to normal. Now if your going to cause other harm to continue to get a fix wether or not you have full control over yourself. Thats harder to say. Because some people would carry this on to get back on the drug after you help them off and some could stay off for the rest of their life. So I do believe that strong addictive drugs can be a case by case basis. If you're talking about weed. I still don't understand why so many people and countries continue negative thinking about it. It has proven itself to be capable of healing many ailments and possibly fixing cancer in many ways. So why not just allow it at this point.
