i went to east africa too about last august. i mean its always a risk but i think u could get away with it. try vaseline and adding layers and layers of wrap that will take care of the odor but dont bring anything back(they only let the k-9's loose after we came back to america), Airport screeners only look for sharp or gun shape objects and bud will only look like the rest of the cluster of shit in your suitcase. the major problem is prolly watering because most of the water is contaminated and u have to buy alot of bottled water.
all your questions were very basic. u should do alot reading first or atleast watch a dvd. ur taking a big risk for something ur not to sure of. do u know the consequences of holding erb in that particular country? holding erb where i was staying gives you a minimum of 10 years and who knows where feeding u dirty bread & water and shit. and thats if the mp's dont beat u or shoot u to death. i hope im not scaring you but seriously rethink this. i would only bring erb to smoke not to grow.
