There should be no worries, product is triple sealed and is sent express post, you even get a tracking number. This place has been in business for a long time without incident and probably ships out pounds a day, huge website. The police are not worried about companies sending out medical weed, it is great for glaucoma and loss of appetite
I will be a repeat customer just because of the quality and selection.
EDIT: For now the police are not allowed to open our mail, they would need a warrant, also you as the receiver do not know what is in the package, for all you know that parcel could be the washer parts you ordered and someone sent you that by mistake unknowing to you. For me there is no real risk as it would take too much effort to search medical weed shipments.
Now if there was an online Meth site it would be shut down.
