ALLEN CARR, de profesie contabil, fumator de pana la 100 de tigari pe zi, a incercat zadarnic, de nenumarate ori, sa se lase de fumat, pana cand, in 1983, a descoperit METODA USOARA (EASY WAY) care ii poarta astazi numele. A infiintat o retea internationala de clinici Allen Carr pentru vindecarea fumatorilor de adictie, a extins METODA USOARA la alte situatii (controlul greutatii, dependenta de alcool etc.), a publicat carti– traduse ulterior in peste 20 de limbi–, insotite adesea de versiuni audio sau video. Printre bestsellerurile sale se numara Allen Carr’s Easyweigh to Lose Weight, Allen Carr’s Easy Way to Stop Smoking, The Only Way to Stop Smoking Permanently, How to Stop Your Child Smoking si The Easy Way to Enjoy Flying.
