Alright well i have this friend who is doing an exchange program this year and is currently in Denmark.
He has found a good source of hash and can score it when ever he wants.
Now my question is would he be able to send it in the mail to Aus? it wont be a lot and he would use a post letter.
also what are the chances it will get caught by customs?

I would say it's more likely to get past than to get caught. AFAIK they don't use drugs on all the mail. Also, if the package is stopped, they send you a letter asking you to claim the package at the post office. If you go, you admit to owning the package (otherwise they cant prove it was a mistaken address or something) and you get in trouble. If you don't go to claim the package nothing happens.

Also, samples or bullshit.

Well i'm still at home so my dad would be claiming the package, so thats a bit of a problem.
but remember it would be in a post letter, any suggestions on how to not get it sent to my house?

PO box?

Friends house?

Don't claim the package?

Just make it worth it... That is what I say. find out the maximum that a packages can weigh, make the whole package of hash and envelope weigh a few grams under that maximum then you will still be able to slide it into a mail box. (Don't have your friend personally hand the package to someone to be delivered)

You have to find out what is going to happen to you if somehow it DOES get caught by customs... What would the charge be? How would you handle it?

Well.. you and your friend have to get a solid understanding of what you would say to an officer at your front door (it COULD happen)

People do this all the time, it is a fairly neat loophole... let the postal service smuggle your drugs for you!!

Don't touch the package in any way, because even though you may not have prints on file now, they can be taken. (If they find the crime worthy)

Just be careful, package the hash with plastic well (so well that you can wash it under your sink with soap and none gets in)

BTW, you really should wash it like I said before it goes into the envelope.

Again, be careful, and the hash should arrive with no problems.

Once your friend sends the package, 2 things can happen:

1. It arrives safely. You get high. Congratulations.
2. It gets caught by teh fedz and they send a "love letter" to your house (or wherever the package was originally sent) asking you to go to the post office to claim your package. By claiming the package you are admitting it is yours. If you don't claim the package they have no way of proving you had anything to do with it being sent to your house. Maybe it was a joke? Maybe a mistake? Sure, they know the truth, but they cant prove shit.

Edit: You cant get stop the smell without vacuum sealing it. If you don't vacuum seal it, any dogs around WILL smell it.
