having used marijuana as recently as last september, and having used it on and off since i was a teenager, i would say that it is not something that is conducive to a strong mind, but neither is alcohol. both can be abused to the point of destroying a life, and we know that God gave wine and strong drink for the purpose of making the heart glad, and for celebration. i would say weed might be a little different, especially nowadays, as it has been grown to 1) be very powerful and 2) have psychotropic properties that are also very powerful, and, quite frankly, dangerous to the mind, imo. there are strains that are bred specifically for medicinal purposes, that have lower thc properties and therefore do not have the same psychological effects. those strains are used for inflammation, pain management, tumor reduction, those kinds of things. the literature on the use for that is growing and mostly positive, i have though about using that strain, as i cannot use most pain medication, as my kidneys are failing, and pain meds, specifically the NSAID class, damage the kidneys.
does any of this help?
