Hello fellow Tornians,

I haven't seen a proper guide on addiction and rehab decay so figured I'd share the work I did together with Wiber over a year ago. It was made for him to use the data to write a comprehensive guide and post it but that bastard quit so I just left it.... until now. This is what we managed to gather before he left. Enjoy!

If you are new to rehab and addiction I suggest you also give Wulfric's guide a read, it has some good stuff.

If you'e in the UK and Imgur no longer works, go here

Addiction

So what's addiction in the world of Torn? Every time you take a drug you will gain some addiction points (AP). As you build up addiction you will build up negative side effects (the getting kicked from education, losing job efficiency, not being able to train without being under the influence of drugs and battle stat reduction). The AP testing for each drug is done with addiction XXV. Because of rounding I can only estimate the AP gain without specials. Love juice is based on numbers from the wiki, since I wasn't able to test that.

To get rid of your addiction you can:
- Wait for natural decay to do it's thing. Natural decays takes away 20 AP per day. When I made the guide it was 21 AP so all calculations are made with 21 AP as natural decay. Allegedly happens somewhere between 2am-4am but haven't tested this personally
-The job special available in a Flower shop, Cruise line agency or nightclub will take away 1 AP per job point.
- Go to rehab in Switzerland.



Battle stat reduction

Building up addiction without rehabbing will give you a passive stat reduction. The battle stat reduction is directly related to the amount of addiction points you have built up. The only thing that will reduce it is the side effects (Reduces passive negatives from drugs and addiction by up to 30%) faction upgrade under that toleration branch. The intervals at which you hit a certain battle stat reduction with the side effects special active seem a bit random. For example it will take almost more than twice the addiction points to reach 20% battle stat reduction with side effects upgrade even if it only reduces negative effects by 30%?! That is because the reduction is on the percentage itself and not the addiction points needed to reach it. So 20% reduction with side effects is the same as having 28% reduction without upgrades.

If you're interested it follows the equation: 143*EXP(x/12). with x being the battle stat reduction in %.

Here's a graph showcasing the difference the side effects upgrade makes.



How long does it take to reach a certain reduction level? This depends on your xanax intake and faction specials. Tables below show how long it will take to reach a certain battle stat reduction level depending on your toleration level and xanax usage.








Rehab decay

One lesser known fact about rehab is that the more you use it the less effective it becomes.In the beginning one rehab will remove around 90 AP (not 100% on this number but it's around there) and by the end one rehab will remove 1 AP. This is known around my condo as the rehab cap. This means that to begin with getting rid of the addiction from 1 xanax will cost just under 100k and at the cap it will cost 8.75m (90 times more!).

What we do know is that it's directly related to the amount of times you have rehabbed. And since rehabs done is a visible stat since September 2015 I've been able to give a decent estimation of rehab decay. Thanks to the players with varying amounts of rehabs done that helped me with this!

NOTE: If you have rehabbed before September 2015 you can't estimate your rehab cost from your rehabs done stat

The cost is without toleration specials.


Rehab cap and when do I reach it?

Once you have reached a certain amount of rehabs you will reach a rehab cap. That is the point when your rehab efficiency stops decaying and your rehab will never be more expensive than this. This will happen when the cost of one xanax is 8.75m (or 1 rehab per AP). That point seems to end up around 20,000 rehabs.

The table below will show you how long it takes to reach the rehab cap depending on how many xanax you are taking, your toleration level and if you're using job points to reduce addiction. Assuming you are using rehab perfectly (not wasting any natural decay and never fully rehabbing).



Example of how your yearly rehab cost grows. Year 8 being where you hit the cap if taking 3 xanax per day.




Another interesting way of looking at cost breakdowns once you have reached the rehab cap:
With no toleration perks each Xanax will cost the user 8.75m on top of the cost of Xanax.
With full toleration perks each Xanax will cost the user 4.5m.
With full toleration and max rehab reduction (20%) each Xanax will cost 3.6m.


Books


There are two books you can read to deal with addiction, here's my advice on how to use them most efficiently


Hot Turkey


Effect: Gain no drug addiction for 31 days.


Value of the book at the rehab cap: 418.5m (3 xanax per day and max toleration assumed)


Before reading this book you should consider two things
1. Use it at a time where you can take as many xanax as possible to fully max out the potential of the book
2. Since you won't gain any addiction for the whole month you should build up addiction before reading the book to make use of natural decay.

Note: You will be kicked out of education and won't be able to join a new course for most of the month. Your employer will also hate you if you aren't miles above the stat requirements.
Note: The reduction is based on you having Side effects X and Addiction XXV, your faction should have it. If they don't, complain! :)

Table shows how much battle stat reduction you should build up before starting to read the book to fully make use of natural decay. The number is dependent on how many rehabs you have done (you can find this in your personal stats).


Over 31 days you will lose 21*31=651 AP. So you need to build up at least that much addiction. I have added some room for going to rehab to restore happiness after an overdose. Since you should really max out your xanax usage while using this book I have assumed you need 3 rehabs i.e. 3 overdoses. Taking 93 xanax while reading the book you're about 88% sure to overdose 3 times or less assuming a 2% OD rate. If you want extra safety, build up some more addiction!

The reason it is different depending on how many rehabs you've done is once again rehab decay. Your rehab is more efficient the fewer rehabs you've done and therefore will remove more addiction if you rehab once to restore happiness. Resulting in you having to build up more addiction before you use the book.



Milk yourself sober


Effect: Removes a substantial amount of drug addiction upon completion.


Value of the book at the rehab cap: 235m per month of building addiction



The data for this book comes from me using the book, Magikarp, and Tig_Rock.

This book removes ~95% of your addiction regardless of addiction level!


Assuming there's no actual cap to how much addiction it removes we can estimate a value of the book. At the rehab cap while using 3 xanax per day this is the amount of savings you can get using the book after x amount of time building up addiction:



That's 14.3b in savings if you can actually hold out for 5 years without a rehab... but also about 50% stat reduction by that time :)

Data this is based on: Addiction points right before finishing to read the book and remaining AP after finishing to read the book


Thanks for reading!
