My thoughts on Marijuana:
It ruins your memory, makes you passive and stupid (in high doses under periods).
Temporarily it just makes you passive and stupid.
I'm not a fan of marijuana, if you're gonna do drugs... Then do it properly!
My thoughts on Ecstacy:
You have complete euphoria and love everything, it feels like you won the world championship sports at the same time and that you just got acknowledged by your crush at the same time.
Makes you stupid, hyperactive.
Continous use causes depression and would actually break serotonin receptors down, which is bad.. Then again you should not do anything too often.
You should not smoke weed every day
You should not take ecstacy every day
You should not drink alcohol every day
If you smoke and drink every weekend, sure it ain't good for you but it doesn't break you anytime soon.
If you pop pills every weekend you will have issues within months.
Then again, you can understand the brain can't handle too much of the goods too often.
Conclusion:
Weed: If you like being passive, keep it to the weekends and dose with consideration. (I know you "can't die" from weed, just shut it)
Alcohol: If you like getting hammered and just feel generally good, go ahead on the weekends. But drink with moderation, it is easier to overdose then weed and affects your common sense a lot more.
Ecstacy: If you want to enjoy yourself like you never had before, do so every few months and dose with consideration, getting serotonin syndrome is not comfortable (i do not know though).
Personal preference: Rolling once every few months, because of the indescribably sensation.
But generally i'd say my soft spot is for beer!
That's my view of things....
Then again i know nothing about this, never taken any drugs.....?
