Was i first time really high?

Okay, so me and my 2 other friends decided to go smoking yesterday after their schoolday was finished and my work ended on my job. We were in somekinda hilltop what was like somekinda park actually, so my friends took out their homemade bong and we started to take hits. First i took pretty small hit but after that i took so massive hit that i was couching like hell and i could not take any of hit after that massive rip. But after that i was feeling like pretty lazy and we walked randomly around the park throwing small rocks down the cliff and laughed for everything almost, walking was more slower than normal and i didnt care about almost everything what was happening, just random acting and stuff. I was driving with my car on that day and it was weird as hell lol, i didnt like feel my bottoms of my foot and i was more careful too, when i came home i checked my eyes from mirror there was slightly red areas in the white area. This wasnt my first time smoking mary jane, this was like 3rd time and i've been smoking ciggys too sometime, still i was coughing like mofo.

 

This is what is bothering me too, im not sure does the smoke goes all the way to my lungs when i inhale or am i doing it right, when i took the hit i inhaled the smoke and hold it for about 3-4 seconds then exhale it.
