White Widow - It was rare to not cough after taking a hit. I was glad to see it go, I hate coughing! After a lengthy cure it went down a little smoother but the smoke expansion got worse. It'll really tear your head off.
serious seeds ak47 is a lung stripper .and kalimist has some phenos that are the same.
but there is a difference in harsh weed that was prepossessed wrong. and strong weed that will expand in your lungs after you take a draw off a joint . its smooth going down but expands when in your lungs filling every hole and void in your lung . your lung is like a sponge it has pockets where air fills it up. when smoking strong or high thc strains thay expands in every pocket.
I have a strain made by jlp named sourdog,. and its smooth going down but feels like glass when trying to hold it down.
