It was juat on the news that a guy sent 250grm of marijuana to one of his friends in cairo egypt.
Unfortunately, they got the egyptian guy when the packege arrived egypt.
Its common also to send cannabis in really good seald bags in packeges within the eu specially between holland and uk and other countrys.
Sometimes the workers in the post office smell the packege then they call the police.
But if its good seald it can work.
YES it can work and it happens alot.
Is it safe NO. NOT 100%
Thats why some ppl devide what they will send to smaller packeges and send from various location
50/50 deal
Good luck play it smart and safe..
