When Bethesda made Fallout 3, they dumbed down chems (they do that a lot with game mechanics) to be nothing but a mere slight bonus with a possible insignificant withdrawal taking chems from being an interesting mechanic and challenge to base your gameplay around to just another "Food" item which creates dissonance with the story as well since you can witness in the quest "High Times" chems have a severe effect on the user but the player can chug themselves full of every single chem known (and unknown) to man and walk it off with a mere -1 Agility; what this mod aims to do is to make chems a more interesting element by restoring the dynamic it had in the classic games while enhancing it to fit into Fallout New Vegas (and 3 if you have TTW).

Update 2.0.2

Added the following into the "Tribal Chems" category which means they're addictive now:
- Healing Powder (10% Addiction chance)
- Leg. Healing Powder (30% Addiction chance)
- Ant Queen Pheromones (50% Addiction chance) 
- Healing Poultice (40% Addiction chance)
- Fiery Purgative (30% Addiction chance)
- Bitter Drink (5% Addiction chance)
- Antivenom (20% Addiction chance)
- Datura Antivenom (50% Addiction chance)

Why?
- to make more use of the "Tribal Chems" category
- to bring survival healing items in-line with Stimpaks since Stimpak Sickness got reworked (See below)

FAQ
Q: Why did you make this mod?
A: Because chems in the base game are just boring and are either used to pass checks, have a little bit more carry weight or to be spammed during intense moments and all behaved the same, this mod breathes life into chems by making them have significant benefits and drawbacks and dividing them into categories to make them further unique just like how fallout 2 & tactics did it.

Q: Why did you change Stimpaks?
A: The only change I made to Stimpaks is to Stimpak Sickness itself which in the base game was exclusive to Super Stimpaks only, all I did was restore how Super Stimpaks worked in the classic games by giving you a quick and immediate recovery but following up with damage, I made the sickness stack and had regular Stimpaks also progress the sickness albeit at 1/5 the rate of Super Stimpaks; the reason behind these changes was because Stimpaks were too much of a crutch in the base game overshadowing any other healing items like healing powder or food, now with this mod Stimpaks are still great! but you might want to use them alongside other healing items to avoid the drawbacks.

Q: Why did you add Overdose?
A: Actually, Overdose was a mechanic in the classic games and since I'm restoring how chems worked in the classic games which is much stronger than in New Vegas it was only natural to restore Overdose as well to avoid the player getting too overpowered, besides since most chems now last for hours you won't need to take them as frequently as before.
