The fact that it doesnt harm your lungs at all which I don\'t even know is true...doesn\'t make it 100% good for you.
It still effects your brain. It can alter your motivation, mental clarity, mental health, memory, etc.
It\'s a drug. It affects the release of the chemicals in your brain that make you experience pleasure like dopeamine. Mainly it releases massive amounts of them at one time when you smoke. This obviously throws off the natural balances and proccess going on up there. After using it for long periods of time it gets harder and harder for your brain to release normal amounts of the right chemicals without the drug. Basically there are many intricate reactions going on in your brain overtime that you are not even aware of and that would probably not be considered positive.
Of course most everyone needs something to take the edge off. And vaporizing marijuana in moderation is pretty safe. But \'100% benefit\' is not true either.
