If you are perfectly content and don’t have an urge to try mind altering substances then don’t bother. What’s the reason to risk building a dependency that might be difficult to shake off?
On the other hand if like many people you suffer from anxiety or depression and find that prescription medicine is ineffective then microdosing drugs can have miraculous effects. THC has helped me deal with anxiety way better than prescription drugs so I now micro dose THC capsules. I’m lucky enough to live in a country where weed and its derivatives are fully legal so I can just go to a store and buy what I need.
