Drugs

Addiction
Every time someone uses an addictive drug, they must make an addiction saving throw; which is a Constitution saving throw with a DC equal to the result of the drug's addiction dice. Each consecutive use of the drug adds an additional addiction dice. Each long rest, the user can make a residual addiction saving throw; which is a Constitution saving throw with a DC equal to to the maximum possible total of their current pool of addiction die. On a success, one addiction die is removed from their pool; on a failure, the user becomes addicted to the drug.

Withdrawal
If a user becomes addicted to a drug, as soon as the drug wears off, the user gains a level of exhaustion. This level of exhaustion can only be removed with Greater Restoration or going a week without the drug. When an addicted user fails an addiction saving throw, they must make a spiraling addiction saving throw; which is a Constitution saving throw with a DC equal to 10 + double the level of permanent exhaustion. On a failed save, the user gains another level of permanent exhaustion while sober.

Overdose
If a user takes a substance while they're already on that substance or one that has a similar effect, they take a number of poison damage equal to double the maximum possible total of their current pool of addiction die for that drug.

Apotheosis
Vector: Injection

Addiction dice: d8

Speed: 6 seconds

Duration: Until the spell slots are used

Effect: Grants the user the ability to cast spells

With enough regulated and continued use, the user gains the ability to cast spells with the ability being forced into their body (gaining a level in warlock). The magic is relatively uncontrollable, as the magic is essentially attempting to escape the body which it cannot inhabit, so it is always cast at it's maximum possible level. Apotheosis must be taken to regain the expended spell slots, experienced users learn to use exactly enough to regain their expended spell slots without overdosing. If a user with an apotheosis addiction overdoses on the drug, their magical power surges even further. For 1d4 x 6 seconds, the users spells are more potent and deal twice as much damage.

Long-term usage of apotheosis can lead to a process called succumbing, which turns the user into monstrous mutant that tends to resemble a massive pile of flesh. The mutations seem to vary from person to person. However, there are some common traits among the mutants, such as elongation of the neck and arms, incredible swelling, and fusion of the head directly to the body. The mutated bodies are often asymmetrical. While some mutations can allow the person to maintain a vaguely human shape, some can be much more distorting and drastic. Some mutations appear to make the person stronger or faster while some make the person appear immobile or simply grotesque. The psychological effect of the transformation is that the mutant completely acts on their primal urges, which more often than not manifests as violence. Not all mutants are violent, however. Some mutants will only be violent for a short period of time or towards only specific people. And once this time period ends, the mutant will pacify, becoming immobile and harmless.
