This isn't an appropriate question for OD.
It is extremely subjective to the individual in question and you'll get a different response from nearly anyone you ask. Drugs can enhance your life or open your mind to new ways of thinking. However there are two sides to that coin. Drugs are addictive by nature so although you may not be dabbling in physically addictive chemicals you are still altering your brain chemistry to obtain an artificially positive enhancement of your life. Crack cocaine is not physically addictive however it can destroy your life in short order. Most hallucinogens are not physically addictive and aren't necessarily known for destroying lives, but there are downsides to them too such as bringing out dormant mental illnesses.
So are drugs worth trying? I'd say if you're relatively happy with your current life then absolutely not. You must realize that human nature will always cause us to feel unsatisfied with our current life regardless of whether you're the wealthiest man on earth. If this wasn't hardwired into our psyche the human race would've died off thousands of years ago. It is this unsatisfactory feeling that causes creation, ingenuity, progress and exploration. Drugs can temporarily create an escape from this feeling and this (among other things) is why they are addictive by nature.
Hope this helps, and I'd suggest moving this to a more appropriate forum.
