Marijuana is a sacred plant that works with the person's best interest in mind. It has been used, and continues to be used to treat serious diseases like Cancer, ADHD, and many more health problems (https://www.naturalnews.com/2018-07-04-10-science-backed-benefits-of-cannabis.html)
Here is a better question... Is Marijuana good for YOU?
This is subjective.
The plant is an enhancer. Perceive it as the NITRO of a CAR (you being the car)
If you know how to drive, it will take you faster where you want to go. If you suck at driving, you will crash immediately.
A certain degree of self-awareness is necessary if you want to control this plant and make it useful to you. Otherwise, you will become its slave (addicted).
Just like with any strong substance - especially with psychoactive - addiction will cause harm - it will hurt your physical, mental, and spiritual condition.
Use it wisely and let it teach you what it has to teach. Let it empower you whenever you truly feel its the case, and control it without exceptions.
