If you qualify and can wait, you can apply for an Identification card for therapeutic uses in order to purchase at one of the three dispensaries available in the state. If not, you will have to find other means in order to obtain it. I do not condone the alternative means, but if you are adamant about it, you would have to find someone that would be willing to sell to you. According to some forums, there are numerous people in the state that sell around colleges. If you decide to go that route, your best bet is to go to a college or college party in NH in order to find someone who will sell to you.
