I'm not saying that if you smoke a bunch of pot or mix all these drugs together, it will necessarily make you smarter. If you do this habitually, it's more probable that you will end up dumber But if used infrequently and with moderation, these drugs can treat and sometimes cure a variety of mental and emotional disorders that 90 of us suffer from, such as depression, anger, anxiety, and lack of motivation All of which reduce and or hinder the development of intelligence. This is possible because the chemicals in these drugs, like so many others we consume e.g. caffeine, sugar , have the ability to alter the way your brain creates neural pathways. This forces a different perspective into your conscious mind, essentially making you a different person. The effects are temporary, but the neural pathways you created under the influence of the drugs will be retained after regaining sobriety. This allows one to change their own view without using reddit For example, chronically depressed people physically have or are using a smaller proportion of neural connections in the brain associated with happiness. One or two relatively small doses of MDMA coupled with therapeutic treatment can create a chain reaction that results in a monumental shift in consciousness, behavior, and emotional inclination and capacity. Who we are, how we think, and how we perceive the world around us is essentially determined by a series of little electric wires. Everything you will ever know or feel will be stored in this network, and it grows new pathways all the time. Where depends on what you're learning. If you were learning German, you would be growing new connections between the Broca's and Wernicke's areas of your brain And I just made a few connections in my arcuate fasciculus by looking that up. If you smoke some pot, and it enhances the flavor of your least favorite health food, or it increases your appreciation for music, or inspires creativity That rubs off. Because of that experience, you will like that food a little more, you'll feel the music a little more, you'll get a little more inspired to create in the future. TLDR Drugs can have a very positive influence on your life, and your intellectual growth. That said, the residual effects of habitually using these drugs are generally not so pleasant.
MDMA, Cannabis, and LSD can be used to increase overall cognitive performance.
