Hitchhiking and camping in Iran

[frippage]

Hey guys : D
I plan to start hitchiking from Poland to Iran in the beggining of the August. Because of that I have some question, that hopefully you'll answer.
1. Is hitchhiking legal in Iran and can I tell border guards/police that I am going to hitchhike?
2. Is camping in a tent legal when not on camping site?
3. May I get in some serious problems for having pepper spray for my own safety with me?
4. May I drink alcohol in Iran if I'm not Muslim? Wikipedia says: "Bringing alcohol into Iran is disallowed for Muslim citizens, but Christians and Jews are allowed."
5. Is the tap water drinkable in Iran?
6. Is it legal to sleep in Iranians apartments/houses after being invited?
Thanks for help, take care ;)

Hi Tom

1- It's legal but new. Still no enough information about this kind of travel.

2- You can use your tent almost in any place you like.

3- Pepper spray is not legal.
Trust me! you never need anything like this.

4- You can drink. But there is no place to buy and no place to drink so it's better forget drink during your trip.

5- Yes. Non drinkable like in parks has sign.

6- Of course it is.

Thanks for a qiuck reply Mehdi!
But I still have one problem to solve. I don't actually know if it's ok to take some medicines, that contain small amounts of illegal substances eg. pseudoephedrine. It's commonly used in some medicines in Poland but I still have some doubts if it will be safe Of course all medicines will be in original packages.

I'm not sure about this medicine. May Be better buy it in Iran.

Yes it is legal but not safe. I suggest you to first take care about your safety and then do something else.
Secondly avoid those places where camping is not allowed or check before start your camping is that area is not used for drugs or anything harmful.
In some of the regions tap water is drinkable but mostly not I suggest you to bring your own water.
