Opinions?

hello, i am 20 and first time using reddit. I participate in lent and try to do good during this time of year. But i want to make a short film since i decided it might lead me into a new hobby. But would it be okay if i used a real/ or fake cigarette? i personally dont smoke but i want to show emotion by doing this, debating to do this tomorrow or the following day. Please respond if you think is best. Thank you!
