I'll be honest: that markup really needs to be put out of its own misery. It's pretty bad. I'm not going to try and offer specific information on how to "fix" it, because frankly, I don't see the point. But for the purposes of education, I'll highlight the problem areas in red (problem meaning the EpubCheck errors) and offer a general course of action.
Code:
<p class="ListParagraph" style="margin-bottom: 5pt; margin-left: 36pt; margin-top: 5pt; text-align: justify; text-indent: -18pt;"><span style="color: rgb(128, 0, 0); font-size: 10pt; line-height: 115%; font-family: Symbol, serif;">·</span><font face="Times New Roman"><span style="font-size: 9px; line-height: normal;">*</span></font><span style="font-size: 16pt; line-height: 115%; color: rgb(128, 0, 0);">kvdsjovsjvofvvfvfdfvdiovfoidfvjdofvjdo</span><span style="font-size: 16pt; line-height: 115%; color: rgb(128, 0, 0);">ityorrjtgietjotrigjovetimboitbmromro</span><br/><span style="font-size: 16pt; line-height: 115%; color: rgb(128, 0, 0);">*</span></p>
As I said, font tags are not valid. Best course of action: incorporate the Times New Roman request into the style attribute of the span the font tags encapsulate, and then delete the font tags. I mean, it's an
asterisk for heaven's sake! All of that extraneous spaghetti code to style a single, solitary asterisk!? By the way, I realize this code was generated by a program of some sort, I'm not blaming you concerning the general mess of things.
Code:
<p class="ListParagraph" style="font-size:16pt; line-height:normal; margin-bottom:5pt; margin-left:36pt; margin-top:5pt; text-indent:-18pt"><span style="font-size:16pt"><span style="font-family:Symbol, serif; font-size:10pt">·</span></span><span style="font:7.0pt 'Times New Roman'"> </span><span style="color:#800000; font-size:16pt">For more info, see</span><span style="font-size:16pt"> </span><a href="ErowidVaults"><span class="Hyperlink" style="font-size:16pt; font-weight:bold">ErowidVaults</span></a><span class="urlexpansion" style="font-size:16pt"> </span><span class="urlexpansion" style="color:#800000; font-size:16pt">(</span><span class="Hyperlink" style="color:#000099; font-size:16pt"><a href="http://www.erowid.org/psychoactives/psychoactives.html">http://www.erowid.org/psychoactives/psychoactives.html</a></span><span class="urlexpansion" style="color:#800000; font-size:16pt">)</span></p>
Unless "ErowidVaults" is a manifested file in your epub (and that's highly unlikely) that is not a valid internal or external url. Get rid of it or correct it.

Same as above. "Kvasar" is not a valid href. Perhaps these were once url fragments and the "#" was dropped along the way?. <a href="#Kvasar" />. I don't know. Again; get rid of it or correct it.
Some line-breaks or general beautifying of that markup would go a long way toward making it at least more readable, too.
