Answer: The people that create these drugs could possibly know if opioids are addictive and I think they do. I also feel like doctors know people's value of things sometimes and they would possibly want to ruin that for those people because they just want their paycheck. The people that make these drugs make these because they also know if someone is in a hospital and they are there for an important reason those doctors are going to give them drugs. Those drugs they make are dangerous and they know that. So, yes I believe they do put people on to addictions.
