You're making the right call by avoiding them, honestly; they're an experience best had when one is young, resilient, highly social, and able to quickly bounce back from any negative side effects. If your shit is already together and you're not constantly in search of novelty or pushing boundaries, there's not much reason to get involved with recreational drug usage. That said, psychedelics like mushrooms or LSD are an entirely different thing, and would be something to try at least once in your life, regardless of age. They're small-dosage, highly profound, six-to-twelve hour experiences that are best described as taking a cosmic shower and cleansing the soul, if done in a positive setting. They're not like taking pills or getting drunk, you don't do them casually or daily for a physical feeling, they're practically a religious experience used for personal enlightenment. Definitely something I think would be a shame for anyone intelligent to not experience before they die, even if you don't get around to it until after you're retired and in your 60s on a beach somewhere. Something cool to read about when you're bored, if nothing else. There's a famous artist, Alex Gray, who makes artwork that gives an idea of what it's like to do psychedelics: https://duckduckgo.com/?q=Alex+Gray+art&iax=images&ia=images
