Does this help?

I'm going to take a practical approach in thinking this through, care to join me? Alrighty then........., let's go.
First, there are the primary strains of cannabis, Sativa and Indica.
Second, and as we all know, Sativa is for the head, Indica is for the body, all things considered.
So, this leads us to Thirds, or Thirdly: When the strain is known, so too shall be the effects, also all things considered. I suppose if the region is known (Nepal, India (various locations), Pakistan, Afghanistan, Morocco, Lebanon, The Netherlands, and so on...) this too would aid in identifying what it probably is, and isn't. Huh? Never mind......
In closing, I would say that asking the tender what they know/think is an absolute beginning to what could be a wonderful experience. Or, you could just buy a gram of the most expensive Hash on the menu and take your chances. Either you are going to spend the day where you're at vegged out, or you will spend the day where you're at trying to answer the following questions - What is the meaning of life and is cannabis one of the secret 11 herbs and spices (KFC Chicken)? ':shock:' ':o' ':lol:'
Oh shit, time to go. I see my nurse heading towards me with a dose of ziprasidone. Yikes..., later. ':P'
