Answer

  1. Epinephrine

Explanation:

Mescalin, LSD and hashish are hallucinogens and they affect the regions of the brain that are responsible for coordination, thought processes, hearing and sight.

Epinephrine is a hormone and a neurotransmitter. It binds to beta-adrenergic receptors on heart muscle cells. This causes the contraction rate of the heart to increase.
