That's circular. You're arguing that it is sinful because it induces a state of mind in which a person cannot give glory to god because it is sinful. See the problem?
Yes, but why can we not give glory to God through Christ after using cannabis? This is my question.
Because God wants us to remain sober. Fact is, Weed causes one to loose his sobriety.
Lets look at the dictionary.
Drunk: pertaining to or caused by intoxication or intoxicated persons.
being in a temporary state in which one's physical and mental faculties are impaired by an excess of alcoholic drink; intoxicated:
The wine made him drunk.
Sober: not intoxicated or drunk.
intoxicated: to affect temporarily with diminished physical and mental control by means of alcoholic liquor, a drug, or another substance, especially to excite or stupefy with liquor.
Both weed and alcohol diminish ones physical and mental control
and both cause intoxication.
