Add universal heath care including addiction treatment. This might or might not include de-penalization of addiction, depending on the jurisdiction. Breakdown this more to make clear what I mean. Besides the obvious complementarity between UBI and universal health care, people get to do this because they are also addicted, not just poor. Some are also manipulated by means of being addicted. The current approach that punishes the addicted instead of treating them only makes this worse. Countries that have made addiction a healthcare issue rather than a criminal one have seen results.
