To clarify preworkout I use .15-.2 of a gram of extract smoked out of a quartz nail and water pipe. I use a similar amount in the evening. I no longer combust any flower and breath much easier because of it. I did use RSO an edible concentrate on the begining to get through the pain in the evening I was eating 150mg-200mg thc in a gelcap in the evening. Vape cartridges are an option but I've never found one I liked. It's fair to not I have a very high tolerance and most people would not know I was under the influence, most people could use far less.
