Still seeing visuals 25+ hours after taking a 200ug tab

Hello everybody, I got some tabs that where advertised as 200ug. I took one at around 7pm and was still seeing visuals as late as 9pm the next day. This was my first time tripping and I'm wondering if this was actually LSD or a different substance. I spent the trip playing video games and I also finished a 1 gram cart in about 10 hours after I first took it (accidently I didn't realise how much I was using it). Is this simply because I had a large dose and a large amount of THC for my first trip or are the tabs fake? Thanks for all replies <3
