I know there are groups out there with the purpose of sharing weed/cigarettes/alcohol/etc., ostensibly with the goal of at least making sure they can have money to pay for more essentials. The groups I am in are not those type and specifically prohibit that kind of mutual aid or help. A few years ago a lady came begging for help for fixing/replacing her pricey vape pen and when her post was removed, kept complaining that "other groups would have provided the help!" Turns out she had been kicked out of those.
