As per the title i have a cigar that i have had for around 4 years that i got on holiday, has been in a plastic case, no cellophane wrap sealing it, will it be ok to smoke?
Only one way to tell. Just smoke it.
Yes, just very slowly so it doesn't expand to fast and split the wrapper.Speaking of old cigars, is it possible to rehydrate old dry cigars?

Some are worth the effort to rehydrate. Your run of the mill $5 stick really isn't, IMHO. A nice fat premium Habano sure, give it a go. Stick it in a cellophane from another cigar, fold the end down, place in humidor. The cello is just porous enough to allow the cigar to slowly slowly suck in moisture from the humidor environment.
If you live in a reasonably humid locale and you don't dry your house into a mini sahara with AC and heat, it might be perfectly smokeable as is.
I am sure you have seen guys dip their cigar in Port or Sherry and light up. Don't do that with a dry cigar. It will split open. The filler expands faster than the wrapper can stretch. Same thing can happen if you place a dry cigar unwrapped in a humidor.
I have smoked cigars that I know were at least 6 or 7 years old, enjoying them very much. The secret is maintaining them in a controlled environment. 4 years is nothing. However, 4 years in poor storage conditions will mean that at the very least, it will not be at its prime. At worst, it will be a less than pleasant experience. Very dry cigars will smoke hot and taste harsh with none of the delightful notes that the critics wax poetic about. They will burn unevenly, maybe split or crack.
Look at the end of the cigar. Gently squeeze it near the end to barely flatten it into a slightly oval cross section. If it springs back to round shape almost immediately then it has good moisture content and physically/mechanically has not suffered much. More likely it will rebound slowly over the course of minutes or even hours. Could be smoked as is, might not be so great, but is a good candidate for careful rehydration. If it doesn't spring back at all or if it cracks and crackles, don't smoke it like that. It might come back in the humidor, it might not, but it isn't fit to smoke as is. Just my dos centavos.
Cigars carelessly stored are often too dry, but they can also be too wet. I live in South Louisiana and poorly stored cigars often find themselves exposed to near 100% humidity and temps in the 90s or 100s or even higher. Tobacco weevils and mold will attack cigars in that condition. I was given an opened but full box of some Romeo Robustos once that had been kept in an attic by the buyer's granddaughter after her grandfather died. They were in horrible shape. Shadows of cigars held together by bands and cello wrapping. Utterly worthless. I wouldn't even bring the box home, for fear of weevil infestation. It was all I could do to retain my composure as I examined them in her presence, thanked her for her generosity, and declined the gift as graciously as I could.
