I don't believe in using anything that alters your mind in any way (and I'm not talking about meds for health reasons.)
Alcohol is worse than marijuana because its poisonous (that's what the buzz is) and you lose control over fine motor skills, your reaction delays quite a bit, memory lapses, increases emotions (sadness, anger) and it's easy to overdose from.
Used in moderation and responsibly, decreases those risk factors, however it's still abused by many in a daily basis (not to mention it's addictive properties.)
Marijuana can delay response time, but not as much of a delay as alcohol. You don't lose control over your motor skills, for the most part. You can't overdose. You can become addicted, but your body won't be nearly as dependent on it as alcohol.
However, these are still negative affects that can cause adverse consequences. On top of all that,it does cause memory loss, destroys brain cells, affect language & comprehension skills, and all those things are long term and affect you even while sober.
One against the other: M is safer than A.
However, going back to my original statement, I don't believe anything that alters the mind in any way is safe.
I don't see any restrictions for M but that doesn't cover the fact that it can and is abused, and a waste of life altogether.
There are so many other constructive things to do with life and I think that should be themain focus for everyone.
Drugs and alcohol are the enemy's deceit.
God bless you...
