Keep at it, don't quit now when you have some growth opportunities ahead. Music is a life long thing, don't put it to an expected schedule of accomplishments.
If you can negotiate the smoking issue, give the band a shot to gain experience playing different material with a drummer.
Meanwhile, keep looking for kindred spirits.
If it helps, I'm 46 and have been in scores of bands since starting out at approx. 20 years old. Didn't have a band right away, was totally into learning songs off of albums and taking lessons. Since then, has been periods of being busy and also nothing going on. Seems to come in phases. Ran into "The" band a few times a long the way and had some good experiences.
My latest: answered an ad to do a fill in gig. Ended up with three 1 hour sets of material to learn for the "audition" a few days before the gig. Did it, wasn't really impressed with their musicianship but the people were fun and they really hustle for gigs. Next day got handed three months of fill in dates and a "please join our band" invitation.
Had another band that's a startup from a couple months ago, but singer had an accident so the band is on hold.
Did a fill in for third band at the startup drummer's request. Not really happy with either fill-in but they resulted in gigs and the performance was adequate. Was semi-happy with startup and might be more so when we can resume.
Meanwhile my life is rich with music at home, and jams when they happen. I watch concerts on YouTube (search for "full concert"), or listen to entire albums on YouTube (search for "full album"), or watch Classic Albums/Behind The Music/Rockumentaries on YouTube when I'm not in the mood to listen to my CD collection.
Focus on developing your technique (

Rock on, my friend!
