It depends on if it is natural or enhanced. If you believe God created the world, He created a natural plant with many benefits, but man has taken His creation and modified it. The natural plant has some mind expansion. .you will tend to examine things closer, although over indulgence can lead to brain inactivity. There is use and abuse. If you learn to use it, it is a benefit, if you allow abuse, it will destroy you. I use it because I am ADHD, when I smoke, I can focus much better on a task, without, I'm scatter brained---mind is off and running in many different directions---maybe it's my job, I'm responsible for much, but "pot" has done me great benefits--work I don't want to do---I get a "buzz", and all I want to do is Kick it's ***---get in there do the job right--gun ho---many I know, testify of the same. I also become more talkative and detailed....I can put it down where the rubber meets the road---I get very descriptive, and motivation to be a perfectionist in my work.
I feel quite relaxed and confident, maybe it's because I can focus on one thing, instead of multiple things, when I'm so called "High"...Many have testified that they really can get "into things", some of the best craftsman I know, use it wisely, and perform great tasks----I can associate---my craftsmanship without "sucks", my craftsmanship with, has been recorded as works of perfection. I am a believer in God, I believe He put it here for a reason---obvious to me, it has been beneficial. I believe in Gen. 1:31 "all things He created were VERY GOOD and man has no right to call it bad, but to each, his own. Moderation is the key.
BUT--there are different strands--some make you hungry, some make you tired, some energize, some help you focus, some you cant get a focus---too strong or too much consumed......the best reality is control, find the strand that most benefits you, without dependence..
