Marijuana is addictive for some people, and woe to them, because it’ll mess up their thinking. It can lead to a false interpretation of reality (mental illness) and therefore suicide. It is almost laughable the way some legislators make it legal, with no idea of the harm it can do.
We are struggling to come to terms with the discoveries of the 20th and 21st Centuries, and not everybody understands them. If we proceed with ignorance, we are sometimes lost, though the good Lord has ways that alleviate our consequent suffering.
Our ways are not His ways, a theme that is repeated several times in the Bible. Fortunately He has ways out of our predicaments, and the Holy Spirit will often reveal them to us. Keep praying.
