yea NH is one of the strictest states in the nation if you cant convince a jury to nullify. really sucks but that is the only thing that would hold me back, and im not sure im still considering thats why im not there yet. i stay in CA where you can grow whatever you need. i really want to head back east though and NH is one of my favorite states and i see almost eye to eye on all their other laws especially like the lack of oppressive gun legislation and lack of sales and income tax. i would want to help change the legislation there but it is so oppressive. i figured being able to argue for nullification on those insane laws would not the most difficult task for a well seasoned lawyer, i would assume your chances would be good. also i would assume that nh would respect property rights more than other states nearby to the point where you would not really be raided without a warrant and the sheriff would need a good reason to get one?
also, IMO Cannabis use and growing is extremely spiritual and the first amendment is clear freedom of religion and its expression, which the kangaroo court ruled they could do away with if the government has a vested interest, which stopping people from using a harmless plant does not qualify IMO.
