am in my fifties, high blood pressure etc. what varieties are there that have little to no "speedy" effects when smoked ? the locally available commercial is notorious for it, & i hate the very thought of having to quit after 41 years of enjoying this most noble of plants. any suggestions ? do i need to go after indica strains exclusively & let them go a mite long, looking for couch lock instead of the rush of sativas ? am open to autos, or most anything that won't make my heart act up. any suggestions welcomed, yet again.
