"Psychedelic drugs like LSD and ecstasy ingredient MDMA have been shown to stimulate the growth of new branches and connections between brain cells which could help address conditions like depression and addiction.

Researchers in California have demonstrated these substances, banned as illicit drugs in many countries, are capable of rewiring parts of the brain in a way that lasts well beyond the drugs' effects."

Microdosing

Basicamente é droga "aos cochichos", a  posse é apesar de tudo ilegal (em alguns países) e os efeitos secundários a médio-longo prazo são completamente desconhecidos:

""Microdosing at a medical level, we know absolutely nothing about," he explains.

"The only way that we can sort out whether or not it works is by doing a blinded, placebo-controlled randomised trial."

He says the dangers of people self-medicating like this are currently completely unknown, and that is where the problem lies.

"The definition of a microdose is that you don't notice the subjective effect, but that doesn't mean it's not having any effect on you‬.

"We don't know what the risks in the long term might be.

"There was some concern before 1970 - when the drugs were being used clinically - that in people who were liable to develop schizophrenia and psychotic disorders, the drugs might actually uncover those problems in some people."
