You need to ask yourself this "Do i have a addictive personality"  First before ever considering altering your conciosness with any psychoactive or entheogenic substances.

Its not that one  can get addicted to the drug,Its that one gets addicted to altering his perception/conciousness. And inevitably sobriety becomes bland and unbearable.

So many use more substances to try and alleviate the boring sobriety.

Ask yourself that question,And sure you can still try them if you do like indulging more than the average person,Its just in my experience i can never indulge in enough to stop doing it for good.
