Anything with a reward at the end can be addictive. If we have to reduce this to just substances, it would be more accurate to say new accessible substances rather than new substances. A rough list of substances that have been identified to date include tobacco, alcohol, ecstasy, cannabis, heroin, cocaine, bonsai, inhalants (glue, uhu, gasoline, paint removers, ether, halothane, etc.), LSD, GHB, some types of mushrooms, ketamine, anabolic steroids, methamphetamine. In recent years, chemical derivatives of cannabis, which have not yet been detected by routine toxicology tests, have also been used.
However, a growing type of addiction today is internet addiction. It has become quite common, especially among adolescents and young adults. While betting and gambling are long-standing addictions, online betting has been added to this. In addition, computer games, internet addiction, virtual shopping addiction are also types of addiction that need to be treated.
