I see a lot of people suggesting various drugs, but a number of them will be a little useless without pain. This can be done with a system of penalties that depends on the damage received by the player, it is also possible to slightly change the natural regeneration, so that drugs have a greater effect on it than a baked potato or rotten flesh. And of course, this should be regulated in the configs, because many players will not really like such changes.
