Doctors do not know how "recreational" drugs work. Police forces worldwide fight drug abuse, but the battle is being lost. Until medications can be developed to stop the euphoric effects almost immediately the battle will rage on.
There are possible benefits from some of these drugs. For example, magic mushrooms are being tested for treating mental conditions by psychiatrists. Neural circuits in the brain are altered by the use of the drug. What actually happens though was unknown, until now.
It was thought that dormant brain cells were being activated, the ones that are used during sleep. It has been discovered, however, that blood flow to the brain is decreased when psilocybin is used. MRIs showed blood flow reductions to the thalamus and cortical regions. The front and back of the brain are separated when the drug is taken. Primary sensory areas still retained good blood flow, while higher association regions became "starved" of blood.
Previous theories in regard to brain stimulation are now completely undermined. With brain separation taking place there are possibilities for medical uses. Depression is believed to be caused to a person's brain being too rigid. Such drugs as psilicybin from magic mushrooms could help by making the brain more "flexible".
