Omusingi gwa sigala ow’ebyuma ebikozesebwa omulundi gumu okuyambako okulekera awo okunywa sigala .

Ng’oggyeeko okwesigamizibwa kw’omubiri, okutondebwa kw’omuze gw’okunywa sigala kwe kwesigama ennyo mu birowoozo. Sigala ow’ebyuma ebikozesebwa omulundi gumu yakolebwa okukyusa sigala ow’ekinnansi. Zisinga okubeera ennyangu era teziyokya n’ennimi z’omuliro eziggule. Bw’oba ​​oyagala okulekera awo okunywa sigala, olina okusooka okukozesa sigala ow’amasannyalaze ng’ekifo ky’okyusaamu. Bw’omala okumanyiira okufuuwa sigala, osobola okukendeeza mpolampola omuze gw’okunywa sigala n’okukendeeza buli kiseera n’okendeeza ku nicotine, bw’otyo n’okendeeza ku byetaago by’omubiri. Enkola y’omubiri (physiology) bw’etuukagana n’embeera, n’eby’empisa nabyo bijja kutandika okukendeeza mpola okwesigamira.
