Physical brain deterioration from drugs?

[sylenth]

pre warning smurf did'nt pay much attention at school to biology for example. smurf was wondering, smurf has heard of the silly myths of swimmers thinking holes melt in ones brain etc... smurf does'nt believe in this that's logic to understand, one can't operate with holes in your brain..

smurf heard from someone & was wondering if ones brain does show any physical signs of damage.

example many years of snorting copious amounts of powder? if you think of how much small pieces of dust or things is going up there. smurf knows how it is to have hectic sinus infections & they can even lead to blindness. this along with the effects of ecstasy to the seratonin on the brain & & & etc...

so does any one know if there has been tumors or different shaping, softening or hardening, collapsing or swelling, build up that has taken place on a persons brain? maybe from a autopsy...?

the body clearly does take strain & show. the kidneys & heart too.

i found this on a site: Brain chemistry. Repeated and chronic use of addictive drugs results in brain changes of unknown reversibility. Drugs can reduce energy use in the brain, change gene function, brain signals, the shape of brain cells, brain networks, and activity in specific brain regions. Some drugs are frankly toxic to the brain. Cocaine promotes spasm of blood vessels resulting in reduced blood flow in human brain. Frequent exposure to amphetamine, methamphetamine, and ecstasy produce toxicity and damage to specific brain cells. Heavy alcohol or inhalant use (e.g. toluene) can produce profound irreversible toxic effects and shrinkage of brain grey matter.
