What happens if you take multiple drugs at the same time? There is not enough space on the internet to fully explain all the possibilities, so go out and explore! However, there are definitely some drugs that should NOT be taken together, as it can be very dangerous and kill you. Make sure you know what to avoid.
No Interaction - These drugs don't really interact much with each other, positively or negatively. You either feel both, or one will drown out the other.
Synergistic - These drugs play well together. They either accentuate aspects of the experience, or enable you to investigate difference experiences at a deeper level.
Antithetical - These drugs will actively cancel each other out or take away some of the experience - usually the higher dose wins.
Dangerous - DO NOT TAKE THESE DRUGS SIMULTANEOUSLY. It is dangerous and you can kill yourself.
