11) Medication - What to do with expired or unused medications? Old meds? Keep under the beds! Don't get cuticals, don't flush pharmaceuticals. That goes for both me and youticals.
12) Cigarette Butts - While cigarettes may give you cancer, that's not the answer to the question Can I flush cigarette butts down the toilet? The answer is no. No ifs, ands, or butts.
13) Hair - Hair. Don't even go there. Whatever is coming off your head or wherever you combs or brushes, don't flushes.
14) Chewing Gums - Gums are for chewing, therefore the term 'chewing gum'. Not for flushing.
15) Cooking Grease and Oil - Why would I want to cook grease and oil? I'm not sure what this is doing on this list of things not to flush. Grease and oil are fat. When fat solidifies..wait a second. Do I care if grease and oil are fat? Go to the gym! I still don't get it.
16) Bleach - You can do quite a few things with bleach. You could take it to the beach, beseech it, reach it, teach it, I'm not quite sure but may be able to impeach it. Don't flush it.
17) Band-Aids - Since Band-Aids are made from plastic that is non-biodegradable, the issue as to whether they can be flushed down the toilet is therefore non-biodebatable.
18) What happened to 18? It disappeared! WTF! I'm going to include the link so you can see what I'm talking about. I hope nothing bad happened to it. Here it is. https://www.surfertoday.com/environment/20-things-you-should-never-flush-down-your-toilet
19) Paint - I'm guessing this could have been 18), but it ain't. It's paint.
20) Cat Litter - If cats litter, they should be subject to fine and/or imprisonment just like everyone else. Why should they be exempt? This really grinds my gears, ya know? As far as their waste, don't flush it down the toilet, ok!
