Methamphetamine (disease)

Methamphetamine is a status effect acquired by taking low-grade methamphetamine. The base duration per dose is 10 * (40 - [current strength]). If the drug is smoked, the duration is longer by 1.5 times. If you are not already on meth, then duration is increased by 600 turns. Also, meth increases hunger by 20 (if current strength is lower than 10) or 30 - [current strength].

If status duration is longer than 600 (High on Meth), then meth increases the character's speed by 50, strength and dexterity by 2, and intelligence and perception by 3. If not (Meth Comedown), it decreases the character's speed by 40, strength by 3, dexterity by 2, and intelligence by 1 (despite the description, which says -2).
