A lower dose strain, or a strain with higher CBD:THC ratio would keep you basically at stage 1/2 all night. The thing about weed is that, if you are getting it legally at a dispensary in a state with strict and enforced testing laws (so not CA), you can get yourself a nice low strength sativa/hybrid while avoiding anything with high CBN (that's the couching chem). You will be buzzed off a hit or two, and you just take another hit every 30-60 minutes or so (everyone's mileage WILL vary). It is just like staying buzzed on alcohol is approximately 1 beer/hr (according to the ancient wisdom of older brother's since the dawn of time). All drugs have their tolerances and and all drugs have people who abuse them and people who are "allergic" to them and should avoid them at all cost.
