Fair point, although the addicts are not actually interested or want to take the methadone as a replacement and is mainly for uncontrollable withdrawal symptoms.

It’s a larger difference gap than plant meat vs animal meat IMO. In other words, not taking methadone could be a life or death difference (or at least the difference between relapse and not).

In the meat debate, you could most definitely get a very close texture/taste without the fake meats if you use the right plants and spices. You don’t need the fake meats in order to replicate and satiate that meat-taste desire.
