I accidentally gave my dad lsd

Tldr : My dad is very religious and I accidentally gave him a tab of acid and I dont know what to do<br><br>I was on a bus at 3am and had a small baggy of LSD <br><br>My dad was waiting at the terminal for me and he arrived right as the bus arrived and I wasnt able to slide the tab in my pocket before he showed up. <br><br>He came with me to a gas station to grab some stuff for his house, and I wanted some water to drink.<br><br>I reached into the bag and gave him a bottle of water, when I reached into the bag again, a small square piece of paper was stuck inside the crease of the plastic bottle flattened. I didnt notice the paper. <br><br>I gave him a water bottle with the LSD tab stuck to it. He drank some, and finished the bottle. A few minutes later, when I noticed the paper flattened, I understood what happened. <br><br>I begged him, and implored him, to tell me the truth, if he drank it. He admitted that he did. I immediately apologized, flattened the tab, and said it was for me but I lost it and so I gave him the water, "just incase I wanted it again later, so I didnt throw it out".<br><br>He laughed, and said it was ridiculous that I would "hide drugs" in the water bottle. He believed me. <br><br>I begged him to tell me if he felt anything different, and he said he didnt feel anything. I said "Good, so its okay". <br><br>He then said "The way I feel about this stuff, even if I did feel something, I would never admit it" (he's a very religious person) <br><br>I left him at his house and went to mine. I realize that it was a very bad idea to keep it a secret, but the alternative is worse. I know that I didnt give him a whole tab and he is a big guy, but I don't know at all how he'll react. He wont admit it if he feels something not normal, and he really doesnt know or understand psychedelics at all. <br><br>I should've just told him at the time and dealt with the consequences then and there, but I'm glad I didnt. <br><br>I dont know what to do though. I don't want to bring it up again. But I dont want him to think that he's losing his mind (which is very well possible). <br><br>What should I do?<br><br>He's not the kind of guy who will happily tell me what he's going through. He'll just be afraid, alone, and confused. <br><br>I can't imagine him tripping and in his house, alone, and freaking out and calling the police, and not understanding whats happening to him at all. He'll think he's possessed maybe. Who knows. <br><br>I dont know what to do. I feel terrible. <br><br>I'm going to his house in a few hours. I planned on not telling him and just acting normal. But I might just bring it up again and tell him the truth so he knows whats happening to him. But I dont know if that's a good idea. He might get more confused and upset if he knows its drugs. He might feel like his brain is going to be permanently warped or something. He's a good guy! He just doesnt know a thing about psychedelics. He knows very little about drugs, and alcohol, in general.
