Make friend of mine used cocaine for his first time 75days ago. He said he did two lines. He also used 25 days ago but he only did 2 bumps. What are the chances of him passing a hair follicle test?

You asked this already but it wasn't your "friend" then, it was you...but the same situation. You already had answers for it.

My friend is in the same boat as I am but he also used previously before within the 90 day zone. I was asking on his behalf

That little of use will not turn a hair test positive. Your "friend" is golden.
