i have a question do you think an addiction to computers and technology is healthier than an addiction to drugs or alcohol? Because if you think about it if you sit in front of a computer for long time you may become fat and you will have diabetes. Next your heart will turn to mush and you will die.
Addiction is a very vague term; abuse would be more proper. You can do either of the things you mentioned, like drugs, drinking, or just constantly using technology. It's the people who do it excessively that are damaged. An addiction is person specific, meaning not anyone can get addicted to any one thing more than someone else can. For example, if I did a drug once and didn't get addicted, you can't say that if someone else does a drug once they won't get addicted either. It's completely possible for them to. Assuming you also want a real answer from me, I would say that an addiction to 2PC ( which is a drug ) would be the worst case scenario. It's something many users take only once, as it overheats your body which causes you to die a slow, painful death.
