I was thinking about taking 30-40 mg for my first time, and i feel like I can handle it. Is it a really bad idea?

i have done my research, and i am pretty sure I can handle 30 mg, and probably 40, but not really sure on that. i have read lots on trip reports on erowid and here, and read every dosage description I could find here+at erowid, watched videos on 2cb, and i would be at home when taking it so it would be a peaceful enviroment. The effects i want would be at 40mg that is why i want to take this much, and while i think there would be no problems, i want to hear more experienced peoples opinion on this matter. What do you think?
