Seeds contain no drugs. Harm prevention website and all. Don't fuck around with illegal activities in shitty countries. Even the US the "justice" system is not fun; in Thailand I imagine it would be worse. A friend of mine studied abroad in Thailand and the father of his host family was high up in the police hierarchy. Chief of something. They had 10 cars all of which had TV's in the front console (this is back before Pimp My Ride(before Pimp was a verb as well)) and his host brother would speed down the middle of two lanes watching bootleg porn while driving. All of that was made possible by bribes and extortion. I hope you have common sense because if you have such little knowledge of drugs I can't imagine that you'd do well in a shady situation in a, potentially(I don't know you), foreign country. I wouldn't suggest it even if I was from said country. Take care.
Peace,

P.S.- Or did I misunderstand you? Do you want to extract "butter" from the seed? I suppose it could be done. I have made macadmia butter (I almost wrote nut butter hehheh) and almond butter. So I suppose you could, not-un-ir-de-technically, make hemp butter, but since this is a drug website I assumed you meant an extraction of the cannabinoids. To make hempseed butter use a food processor or if you're feeling industrious: a mortar and pestle. Mash it to whatever consistency you like. However, with hempseeds, you'll want to grind it quite small as those pesky little guys like to fit spots in your teeth to get stuck... well tarnation! Add a little bit of salt to taste and there you have it. A delicious spread that can be used on anything from toast points to rye crackers; the neighbors will say, "Yum."
