In March, Gov. Andrew Cuomo signed the Marijuana Regulation and Tax Act (MRTA) into law. MRTA, among other things, legalized the use of recreational marijuana for adults aged 21 and over. Moreover, MRTA outlined a broad regulatory structure through which recreational marijuana will be cultivated, distributed, sold, and consumed. MRTA also permits individuals to grow cannabis plants at home, subject to certain regulations and limitations. Since marijuana remains illegal under federal narcotics law (see Controlled Substance Act, 21 U.S.C. 812), large questions loomed for New York attorneys as to whether they could provide legal services to the wide-range of clients that are already (or plan to be) engaged in activities authorized by MRTA and/or for attorneys to otherwise engage in conduct permitted under MRTA, which would be illegal under federal law.
