How Drugs Affect Different Personality Types

I was doing yoga earlier when I had this sudden insight or (Ni) moment. It seems to me that drugs affect different personality types differently.

Most people would think that substance use would be used by people in order to change their personality - and perhaps access their subconscious or shadow elements. 

However, it seems to me that drugs actually serve to exacerbate our dominant function. It makes more sense to me that we would become dependent on a substance that allows us to indulge either our first two functions or the first and third which share the attitude that we prefer.  

Therefore, I don't see all substance use as a fork of escapism, but often we don't realize that if we do over-engage certain functions - we ignore the others. And so, in order to become whole and balanced - which should be our goal with understanding these functions, we must make sure that we develop all of our conscious functions and not only the ones that feel comfortable developing.

Since we enjoy the attitude of our first function the most - here is where the danger of becoming stuck in a cognitive function loop. But we mostly seem to stay within our dominant or preferred function whilst under the influence.
