Addiction

Summary

Whenever you consume an addictive drug, there is a chance that you will become addicted to it if you aren't already. Some substances are more addictive than others and have a higher chance to cause addiction. The traits Addictive Personality and Addiction Resistant modify this chance. If you are already addicted, consuming the substance will sate any cravings, as well as potentially increasing the intensity of the addiction.

While you are addicted, you will suffer negative effects. Different addictions have different effects. The more intense your addiction is, the more severe the effects. Taking a drug when you're craving it resets your "sated" timer to 2 hours (1 hour if you have the Addictive Personality trait, 6 hours if you have the Addiction Resistant trait). You start suffering from withdrawal once the timer has run out. Taking a drug when you're not yet craving increases the timer by half as much.

Addictions take a while to remove; it depends on how intense the addiction is. Each time you take the drug, there is a chance your addiction intensity will increase by 1. Addictions have no effect until they reach intensity 3, meaning you can take the drug a couple times safely so long as you then lay off it for a while.

When you have been craving a drug for (6 hours - 10 mins * addiction intensity), your addiction level is reduced by 1, or removed completely if it is 2 or less. (If you have Addictive Personality, the formula is (10 hours - 10 mins * addiction intensity), which yields a time from maximum withdrawal onset to clearing the debuff of 6 days, 21 hours. If you have Addiction Resistant the formula is (3 hours - 10 mins * addiction intensity).) At the lowest level of addiction (intensity 3), it will take 5 hours 30 minutes after cravings start for the intensity to drop to 2, then another 5 hours and 40 minutes for the addiction to be resolved, for a total of 11 hours 10 minutes. At the highest level of addiction (intensity 20), it will take 3 hours 20 minutes after cravings to drop to intensity 19, 3h 30m to drop to 18, and so on. Going from intensity 20 to clear of addiction takes 78 hours 50 minutes, or a little over 3 days. This is the same regardless of the type of addiction.

Post-apocalyptic rehab procedure is to stock some food and water, usually MREs, chunks of meat, and water, along with a hotplate or water purifier if needed, and sit it out for a day or two. The most common addiction, painkiller, can be a real trouble. If you have the "Inconspicuous" perk, then most anywhere without a window will suffice, others may want to hide out in the woods, a basement, or the ground floor of a lab to remain safe.

Addiction Effects

In general, addiction effects are triggered more frequently if your addiction intensity is higher. You will receive a message every time the morale effect is triggered.

Nicotine Withdrawal

• Reduces morale by −15 per trigger, down to a minimum of −3 * intensity.
• Has a small chance to fatigue the player.
• Has a small chance to reduce stimulant level by one, up to a maximum of 50 points of depressant.

Caffeine Withdrawal

• Reduces morale by −5 per trigger, down to a minimum of −30.
• Has a high chance of reducing stimulant level by one, up to a maximum of 150 points of depressant.
